Hadronic versus Leptonic Origin of Gamma-Ray Emission from Supernova Remnants by Nicholas J. Corso, Rebecca Diesing, Damiano Caprioli

“…However, it remains uncertain whether this γ -ray emission arises primarily from the decay of neutral pions produced by very-high-energy hadrons, or from inverse-Compton and/or bremsstrahlung emission from relativistic leptons. By applying a semi-analytic approach to non-linear diffusive shock acceleration, and calculating the particle and photon spectra produced in different environments, we parameterize the relative strength of hadronic and leptonic emission. …”

Flavor-dependent U(1) extension inspired by lepton, baryon and color numbers by Duong Van Loi, Phung Van Dong

“…For this aim, the U(1) charge, called X, is expressed as $$X=x B+y L$$ X = x B + y L in which x and y are free parameters as functions of flavor index, e.g. for a flavor i they take $$x_i$$ x i and $$y_i$$ y i respectively, where B and L denote normal baryon and lepton numbers. Imposing a relation involved by the color number 3, i.e. …”

Explaining the hints for lepton flavour universality violation with three S 2 leptoquark generations by Andreas Crivellin, Benjamin Fuks, Luc Schnell

“…However, in the minimal setup with a single leptoquark generation, a common explanation for all these issues is not possible as this would lead to unacceptably large charged lepton flavour violation. We therefore propose a model with three generations of S 2, each coupling exclusively to a single lepton flavour, i.e. a model extending the Standard Model particle content by an electroquark, a muoquark and a tauquark. …”

Exploring mixed lepton-quark interactions in non-resonant leptoquark production at the LHC by João Gonçalves, António P. Morais, António Onofre, Roman Pasechnik

“…The fact that transitions between different generations of quarks and leptons may exist, the potential of the search presented in this article can be used, as a reference guide, to enlarge significantly the scope of searches performed at the LHC to flavour off-diagonal channels, in a theoretically consistent approach. …”

Sensitivity prospects for lepton-trijet signals in the $$\nu $$ ν SMEFT at the LHeC by Gabriel Zapata, Tomás Urruzola, Oscar A. Sampayo, Lucía Duarte

“…In this work we study the prospects of the future LHeC electron-proton collider to discover or constrain the $$\nu $$ ν SMEFT interactions, performing the first dedicated and realistic analysis of the well known lepton-trijet signals, for both the lepton flavor violating $$p ~ e^{-} \rightarrow \mu ^{-} + 3 \textrm{j}$$ p e - → μ - + 3 j (LFV) and the lepton number violating $$p ~ e^{-} \rightarrow \mu ^{+} + 3 \textrm{j}$$ p e - → μ + + 3 j (LNV) channels, for HNLs masses in the electroweak scale range: $$100 ~{\textrm{GeV}} \le m_N \le 500 ~{\textrm{GeV}}$$ 100 GeV ≤ m N ≤ 500 GeV . …”
