Probing new physics signals with symmetry-restored Yukawa textures

European Physical Journal C: Particles and Fields, 2020
We implement a symmetry violation guideline into a two-Higgs-doublet model embedded with three right-handed neutrinos, and exploit the generic Yukawa structures of the model via a hypothetical symmetry restoration of a global $$U_Q(1)^3\times U_L(1)^3 ...

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models

Fortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Nuclear suppression of the $$\phi $$ ϕ meson yields with large $$p_T$$ p T at the RHIC and the LHC

European Physical Journal C: Particles and Fields, 2017
We calculate $$\phi $$ ϕ meson transverse momentum spectra in $$\mathrm{p}+\mathrm{p}$$ p + p collisions as well as their nuclear suppressions in central $$\mathrm{A}+\mathrm{A}$$ A + A collisions both at the RHIC and the LHC in LO and NLO with the QCD ...

Generation of Quantum Vortex Electrons with Intense Laser Pulses

Advanced Science, Volume 11, Issue 41, November 6, 2024.
Wave functions of high‐energy electrons can be manipulated with ultra‐short intense laser pulses. Nonlinear scattering theory illustrates the efficient transfer of numerous spin angular momenta of laser photons to orbital angular momenta of scattered electrons, twisting electron wave functions into quantum vortex states.

Rare W → B c + γ decay up to the NNLO and NLL accuracy in QCD

Journal of High Energy Physics
We perform a detailed theoretical study of the rare radiative decay of the W boson into a B c meson and an on-shell photon. The decay amplitude is described by two independent form factors, which are calculated up to the next-to-next-to-leading order ...

Search for neutrinoless tau decays tau -> 3l and tau -> l K0S

, 2002
Neutrinoless tau-lepton decays into either three leptons (tau- -> l1- l2 l3) or one lepton and one K0S meson(tau- -> l- K0S) where lepton l means either an electron or muon, have been searched for using 48.6 fb^{-1} of data collected with the Belle ...

The scalar unparticle effect on the charged lepton electric dipole moment

, 2007
We study the charged lepton electric dipole moment which is induced by the scalar unparticle mediation and we predict the appropriate range for the free parameters appearing in the effective lagrangian which drives the unparticle-standard model lepton ...

Leptogenesis from Spin-Gravity Coupling Following Inflation

, 2006
The energy levels of the left and the right handed neutrinos is split in the background of gravitational waves generated during inflation which in presence of lepton number violating interactions gives rise to a net lepton asymmetry at equilibrium ...

High-scale leptogenesis with three-loop neutrino mass generation and dark matter

, 2016
We demonstrate a common origin for high-scale leptogenesis and three-loop neutrino mass generation. Specifically we extend the standard model by two real singlet scalars, two singly charged scalars carrying different lepton numbers and two or more ...
