Clara Peset, Antonio Pineda, Oleksandr TomalakWe review determinations of the electric proton charge radius from a diverse set of lowenergy observables. We explore under which conditions it can be related to Wilson coefficients of appropriate effective field theories. This discussion is generalized to other lowenergy constants. This provides us with a unified framework to deal with a set of lowenergy constants of the proton associated with

Pasquale Di BariThe understanding of the physical processes that lead to the origin of matter in the early Universe, creating both an excess of matter over antimatter and a dark matter abundance that survived until the present, is one of the most fascinating challenges in modern science. The problem cannot be addressed within our current description of fundamental physics and, therefore, it currently provides a very

Seong Youl Choi, Jae Sik Lee, Jubin ParkWe make an updated review and a systematic and comprehensive analysis of the decays of Higgs bosons in the Standard Model (SM) and its three welldefined prototype extensions such as the complex singlet extension of the SM (cxSM), the four types of two Higgsdoublet models (2HDMs) without treelevel Higgsmediated flavorchanging neutral current (FCNC) and the minimal supersymmetric extension of the

Photon–photon physics at the LHC and laser beam experiments, present and future Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20210624
L. Schoeffel, C. Baldenegro, H. Hamdaoui, S. Hassani, C. Royon, M. SaimpertUnder certain running conditions, the CERN Large Hadron Collider (LHC) can be considered as a photon–photon collider. Indeed, in proton–proton, proton–ion, ion–ion collisions, when incoming particles pass very close to each other in very peripheral collisions, the incoming protons or ions remain almost intact and continue their path along the beam axis. Then, only the electromagnetic (EM) fields of

Flavour anomalies in heavy quark decays Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20210601
J. Albrecht, D. van Dyk, C. LangenbruchRecent measurements of bhadron decays show a pattern of consistent tensions with the respective Standard Model (SM) predictions. These tensions appear both in the sector of rare flavourchanging neutral currents and in treelevel semileptonic bhadron decays. Flavourchanging neutralcurrent decays are loopsuppressed in the SM and are thus very susceptible to contributions from new heavy particles

Craig D. Roberts, David G. Richards, Tanja Horn, Lei ChangThere are two mass generating mechanisms in the standard model of particle physics (SM). One is related to the Higgs boson and fairly well understood. The other is embedded in quantum chromodynamics (QCD), the SM’s strong interaction piece; and although responsible for emergence of the roughly 1 GeV mass scale that characterises the proton and hence all observable matter, the source and impacts of

Wolfgang Lucha, Dmitri Melikhov, Hagop SazdjianThe generalization of the color gauge group SU(3) to SU(Nc), with Nc taking arbitrarily large values, as had been proposed and developed by ’t Hooft, has allowed for a decisive progress in the understanding of many qualitative, as well as quantitative, aspects of QCD in its nonperturbative regime. In particular, the notion of valence quarks receives there a precise meaning. The present work reviews

How does Clifford algebra show the way to the second quantized fermions with unified spins, charges and families, and with vector and scalar gauge fields beyond the standard model Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20210702
N.S. Mankoč Borštnik, H.B. NielsenFifty years ago the standard model offered an elegant new step towards understanding elementary fermion and boson fields, making several assumptions, suggested by experiments. The assumptions are still waiting for an explanation. There are many proposals in the literature for the next step. The spinchargefamily theory of one of us (N.S.M.B.) is offering the explanation for not only all by the standard

D.J. Hinde, M. Dasgupta, E.C. SimpsonQuasifission competes with fusion, and can suppress the cross sections for formation of heavy elements by orders of magnitude. Its understanding is important both to map out opportunities to synthesise superheavy elements and isotopes, and to understand the nonequilibrium dynamics that controls heavy ion reactions. A review of experimental studies of quasifission is presented, summarising significant

E. van Beveren, G. RuppThe importance of $S$matrix unitarity in realistic meson spectroscopy is reviewed, both its historical development and more recent applications. First the effects of imposing $S$matrix unitarity on meson resonances is demonstrated in both the elastic and the inelastic case. Then, the static quark model is revisited and its theoretical as well as phenomenological shortcomings are highlighted. A detailed

Casimir force on a light front Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20210301
S.S. Chabysheva, J.R. HillerDepending on the point of view, the Casimir force arises from variation in the energy of the quantum vacuum as boundary conditions are altered or as an interaction between atoms in the materials that form these boundary conditions. Standard analyses of such configurations are usually done in terms of ordinary, equaltime (Minkowski) coordinates. However, physics is independent of the coordinate choice

Michael Block, Mustapha Laatiaoui, Sebastian RaederThe interest to perform laser spectroscopy in the heaviest elements arises from the strong impact of relativistic effects, electron correlations and quantum electrodynamics on their atomic structure. Once this atomic structure is well understood, laser spectroscopy also provides access to nuclear properties such as spins, mean square charge radii and electromagnetic moments in a nuclearmodel independent

What comes after the standard model? Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20210101
M. KhlopovAbstract The standard model (SM) of elementary particles involves particle symmetry and the mechanism of its breaking. It finds no contradictions in the collider experiments, but appeals to extensions for solutions of its internal problems and in view of its evident incompleteness. The paradigm of the modern cosmology is based on inflationary models with baryosynthesis and dark matter/energy that involves

John F. Donoghue, Gabriel MenezesIn the understanding of the fundamental interactions, the origin of an arrow of time is viewed as problematic. However, quantum field theory has an arrow of causality, which tells us which time direction is the past lightcone and which is the future. This direction is tied to the conventions used in the quantization procedures. The different possible causal directions have related physics  in this

M. Anselmino, A. Mukherjee, A. VossenThe nucleons (protons and neutrons) are by far the most abundant form of matter in our visible Universe; they are composite particles made of quarks and gluons, the fundamental quanta of Quantum Chromo Dynamics (QCD). The usual interpretation of the nucleon dynamics in high energy interactions is often limited to a simple onedimensional picture of a fast moving nucleon as a collection of colinearly

M. Biassoni, O. CremonesiAbstract Neutrinoless doublebeta decay (0 ν β β ) is a hypothetical nuclear transition which violates leptonnumber conservation and is therefore forbidden by the Standard Model of particle physics. Its observation would unambiguously demonstrate that neutrinos are Majorana particles and would provide unique information about the ordering and absolute scale of neutrino masses. This would have fundamental

No LandauGinzburgWilsoniantype phase transition is involved. The microscopic DoF of QCD possibly intervening at high baryonic density are traded in for fractionalized topological objects. Essential in the description

Status of the determination of the electronneutrino mass Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20200701
Amand FaesslerAbstract (1) The classical way to determine the electron antineutrino mass is the single Beta Decay of Tritium [3H → 3He + e − + ν e c ] (Particle Physics Booklet, 2014; Aker et al., 2019). This special decay is favored by the small Qvalue Q = 18 . 5737 ± 0.00025 keV (Aker et al., 2019). Presently KATRIN (Aker et al., 2019) yields an upper limit of 1.1 eV (90% CL) for the neutrino mass the best result

Strong coupling constant and quark masses from lattice QCD Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20200701
Javad Komijani, Peter Petreczky, Johannes Heinrich WeberWe review lattice determinations of the charm and bottom quark masses and the strong coupling constant obtained by different methods. We explain how effective field theory approaches, such as NonRelativistic QCD (NRQCD), potential NonRelativistic QCD (pNRQCD), Heavy Quark Effective Theory (HQET) and Heavy Meson rooted AllStaggered Chiral Perturbation Theory (HMrAS$\chi$PT) can help in these determinations

Smallscale structure of fuzzy and axionlike dark matter Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20200701
Jens C. NiemeyerAxionlike particle (ALP) dark matter shows distinctive behavior on scales where wavelike effects dominate over selfgravity. Ultralight axions are candidates for fuzzy dark matter (FDM) whose de Broglie wavelength in virialized halos reaches scales of kiloparsecs. Important features of FDM scenarios are the formation of solitonic halo cores, suppressed smallscale perturbations, and enhanced gravitational

Collision dynamics at medium and relativistic energies Prog. Part. Nucl. Phys. (IF 16.281) Pub Date : 20200701
M. ColonnaRecent results connected to nuclear collision dynamics, from low up to relativistic energies, are reviewed. Heavy ion reactions offer the unique opportunity to probe the complex nuclear manybody dynamics and to explore, in laboratory experiments, transient states of nuclear matter under several conditions of density, temperature and charge asymmetry. From the theoretical point of view, transport models
