Neutrino mass from bremsstrahlung endpoint in coherent scattering on nuclei / Millar, Alexander ; Raffelt, Georg ; Stodolsky, Leo ; Vitagliano, Edoardo
We calculate the coherent bremsstrahlung process ν+NN+ν+γ off a nucleus N with the aim of revealing the neutrino mass via the photon endpoint spectrum. [...]

Fermion mass hierarchy and double seesaw mechanism in a 3-3-1 model with an axion / Dias, A. G. ; Leite, J. ; Lopes, D. D. ; Nishi, C. C.
We present a model based on the SU(3)CSU(3)LU(1)X gauge symmetry that relates the mass hierarchy of the fermions with the solution to the strong CP problem through the U(1)PQ Peccei-Quinn symmetry. [...]

N=2 supersymmetric higher spin gauge theories and current multiplets in three dimensions / Hutomo, Jessica ; Kuzenko, Sergei M. ; Ogburn, Daniel
We describe several families of primary linear supermultiplets coupled to three-dimensional N=2 conformal supergravity and use them to construct topological BF-type terms. [...]

Nonperturbative strange-quark sea from lattice QCD, light-front holography, and meson-baryon fluctuation models / Sufian, Raza Sabbir ; Liu, Tianbo ; de Téramond, Guy F. ; Dosch, Hans Günter ; et al
We demonstrate that a nonzero strangeness contribution to the spacelike electromagnetic form factor of the nucleon is evidence for a strange-antistrange asymmetry in the nucleon’s light-front wave function, thus implying different nonperturbative contributions to the strange and antistrange quark distribution functions. [...]

Optimal observables for Z models in annihilation leptonic processes / Gulov, A. V. ; Moroz, Ya. S.
The optimal observables with the best ratio of signal to statistical uncertainty are proposed for a bunch of popular models of the Z boson. [...]

Schwinger-Dyson equations in Coulomb gauge consistent with numerical simulation / Cooper, Patrick ; Zwanziger, Daniel
In the present work, we undertake a study of the Schwinger-Dyson equation (SDE) in the Euclidean formulation of local quantum gauge field theory, with Coulomb gauge condition iAi=0. [...]

Electroweak phase transition in the scale invariant standard model / Ghorbani, Parsa Hossein
In an extension to the scale invariant standard model by two real singlet scalars s and s in addition to the Higgs field, we investigate the strong first-order electroweak phase transition as a requirement for baryogenesis. [...]

Challenges with large transverse momentum in semi-inclusive deeply inelastic scattering / Gonzalez-Hernandez, J. O. ; Rogers, T. C. ; Sato, N. ; Wang, B.
We survey the current phenomenological status of semi-inclusive deeply inelastic scattering at moderate hard scales and in the limit of very large transverse momentum. [...]

Complete Lorentz-to-Galileo dictionary for direct dark matter detection / Del Nobile, Eugenio
We determine the most general nonrelativistic theory of dark matter (DM)-nucleon scattering complying with the sole requirement of Lorentz invariance, for spin-0 and spin-1/2 DM. [...]
