Two Types of q$$ q $$‐Gaussian Distributions Used to Study the Diffusion in a Finite Region
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this work, we explore both the ordinary q$$ q $$‐Gaussian distribution and a new one defined here, determining both their mean and variance, and we use them to construct solutions of the q$$ q $$‐deformed diffusion differential equation. This approach allows us to realize that the standard deviation of the distribution must be a function of

CP violation in loop-induced diboson production
Journal of High Energy PhysicsWe consider the impact of CP-violating Higgs and top interactions on diboson production from gluon fusion within the Standard Model Effective Field Theory framework.

Scrutinizing a hidden SM-like gauge model with corrections to oblique parameters
European Physical Journal C: Particles and Fields, 2023 In view of the recent high precision measurement of the Standard Model W boson mass at the CDF II detector, we compute the contributions to the oblique parameters S, T and U coming from the two additional Higgs doublets (one inert and one hidden) as well

A variant two-Higgs doublet model with a new Abelian gauge symmetry
Physics Letters B, 2019 We consider a two-Higgs doublet model extended with a broken Abelian gauge symmetry under which all Standard Model (SM) quarks, fourth generation fermions and a new SM-singlet scalar boson are charged.

Effect of gauge boson mass on chiral symmetry breaking in QED$_{3}$
, 2002 In three-dimensional quantum electrodynamics (QED$_{3}$) with massive gauge boson, we investigate the Dyson-Schwinger equation for the fermion self-energy in the Landau gauge and find that chiral symmetry breaking (CSB) occurs when the gauge boson mass $\

Physics of Electroweak Gauge Boson [PDF]
arXiv, 2003 The study of gauge bosons is interesting in two respects. The properties of gauge bosons are modified by higher order effects that are sensitive to mass scales not directly accessible to experiment. On the other hand interactions amongst gauge bosons are sensitive to the symmetry structure of the theory where especially the interactions involving ...

Improving fermion mass hierarchy in grand gauge–Higgs unification with localized gauge kinetic terms
European Physical Journal C: Particles and Fields, 2020 Grand gauge–Higgs unification of five dimensional SU(6) gauge theory on an orbifold $$S^1/Z_2$$ S 1 / Z 2 with localized gauge kinetic terms is discussed.

, 2005 Higgsless models with fermions whose SU(2) properties are "ideally delocalized," such that the fermion's probability distribution is appropriately related to the W boson wavefunction, have been shown to minimize deviations in precision electroweak ...

Advanced Quantum Technologies, EarlyView.The critical parameters and energies, at which the wave function of the Bose Einstein Condensate in a double well trap exhibit the symmetry breaking, are estimated. The phase space representation of the states is obtained trough the Wigner function and the trends of the negativities are analyzed.
