This review provides both a comprehensive summary of the current status, as well as an accessible entry point for phenomenologists with interests in dark matter, Higgs and electroweak or neutrino and flavour physics in the context of a wide range of BSM scenarios. It begins with a qualitative overview of the field and a collection of key properties and typical results. It then focuses on model-independent, generic formulas and classifies types of BSM scenarios with or without chiral enhancements. A strong emphasis of the review are the connections to a large number of other observables — ranging from the muon mass and the muon–Higgs coupling and related dipole observables to dark matter, neutrino masses and high-energy collider observables. Finally, we survey a number of well-motivated BSM scenarios such as dark photons, axion-like particles, the two-Higgs doublet model, supersymmetric models and models with leptoquarks, vector-like leptons or neutrino mass models.

The potentials consist of local and non-local potentials due to (i) One-boson exchanges (OBE), which are the members of nonets of pseudoscalar-, vector-, scalar-, and axial-vector mesons, (ii) Two pseudoscalar exchange (TPS), (iii) Meson-Pair-exchange (MPE) and (iv) Diffractive exchanges. Both the OBE- and Pair-vertices are regulated by Gaussian form factors producing potentials with a soft behavior near the origin. Broken SU(3) symmetry serves to connect the NN, YN and YY channels. In particular, the meson–baryon coupling constants are calculated via SU(3) using the coupling constants of the NN-analysis as input. The assignment of the cut-off masses for the BBM-vertices is dependent on the SU(3)-classification of the exchanged mesons for OBE, and a similar scheme for MPE.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Purpose:&lt;/h3&gt;&lt;div&gt;The NN,YN,YY results presented are those from ESC16, which is the latest version of the ESC-potential model for Baryon–Baryon (BB) scattering. The two body BB-potentials are also applied to the hyperonic many-body systems. Next to the standard ingredients of the ESC-models, in the ESC16 version a contribution of the short range repulsion due to the quark Pauli-principle in the BB-channels has been included systematically for the first time.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods:&lt;/h3&gt;&lt;div&gt;In this review the (new) derivation of the potentials is based on the formulation of relativistic quantum field theory (RQFT) as developed by Kadyshevsky. Here, in contrast to the usual Feynman formulation, the particles in the Kadyshevsky graphs remain on-mass-shell also in the intermediate states. This implies that Gaussian form factors, a characteristic of the soft-core models, are well-defined and can be handled easily in the Kadyshevsky formalism. Furthermore, pair-suppression can be handled phenomenological by introducing factors at the vertices without conflict with relativistic invariance.&lt;/div&gt;&lt;div&gt;Major novel ingredients with respect to the former versions ESC04–ESC08 is the inclusion of (i) short-range Odderon-potentials corresponding to the odd numbers of gluon-exchanges next to the Pomeron-potentials representing the even number of gluon-exchanges, (ii) short range repulsion in all NN, YN and YY channels due to Pauli-forbidden six-quark cluster &lt;span&gt;&lt;math&gt;&lt;msup&gt;&lt;mrow&gt;&lt;mrow&gt;&lt;mo&gt;(&lt;/mo&gt;&lt;mn&gt;0&lt;/mn&gt;&lt;mi&gt;s&lt;/mi&gt;&lt;mo&gt;)&lt;/mo&gt;&lt;/mrow&gt;&lt;/mrow&gt;&lt;mrow&gt;&lt;mn&gt;6&lt;/mn&gt;&lt;/mrow&gt;&lt;/msup&gt;&lt;/math&gt;&lt;/span&gt;-configurations.

A proper treatment of the effects produced by magnetic fields during the dynamical evolution of these systems can help to understand observables that otherwise show puzzling behavior. Furthermore, when these fields are comparable to or stronger than <span><math><msub><mrow><mi>Λ</mi></mrow><mrow><mtext>QCD</mtext></mrow></msub></math></span>, they serve as excellent probes to help elucidate the physics of strongly interacting matter under extreme conditions of temperature and density. This work provides a detailed report that contains in-depth analysis and expert insights into the specific topic of the effects of strong magnetic fields on QED and QCD systems. In this sense, the report is intended as a white paper contribution to the field. The subjects developed include the modification of meson static properties such as masses and form factors, the chiral magnetic effect, the description of anomalous transport coefficients, superconductivity in extreme magnetic fields, the properties of neutron stars, the evolution of heavy-ion collisions, as well as effects on the QCD phase diagram. We describe recent theory and phenomenological developments using effective models as well as LQCD methods. The work was motivated by presentations and discussions during the “Workshop on Strongly Interacting Matter in Strong Electromagnetic Fields” that took place in the European Centre for Theoretical Studies in Nuclear Physics and Related Areas (ECT*) in the city of Trento, Italy, September 25–29, 2023.</div></div>","PeriodicalId":412,"journal":{"name":"Progress in Particle and Nuclear Physics","volume":"146 ","pages":"Article 104199"},"PeriodicalIF":17.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
