Gauge transformations of Spin-Orbit interactions in graphene
, 2015 Inclusion of spin-dependent interactions in graphene in the vicinity of the Dirac points can be posed in terms of non-Abelian gauge potentials. Such gauge potentials being surrogates of physical electric fields and material parameters, only enjoy a ...

Topflavor: A Separate SU(2) for the Third Family [PDF]
, 1996 We consider an extended electroweak gauge group: SU(2)$_1 \times$ SU(2)$_2 \times$ U(1)$_Y$ where the first and second generation of fermions couple to SU(2)$_1$ and the third generation couples to SU(2)$_2$.

Gap Equations and Electroweak Symmetry Breaking [PDF]
, 2006 Recently a new dynamical symmetry breaking model of electroweak interactions was proposed based on interacting fermions. Two fermions of different SU(2) representations form a symmetry breaking condensate and generate the lepton and quark masses.

Fermionic Field Theory and Gauge Interactions on Random Lattices
, 1993 Random-lattice fermions have been shown to be free of the doubling problem if there are no interactions or interactions of a non-gauge nature. However, gauge interactions impose stringent constraints as expressed by the Ward-Takahashi identities which ...

Gravitino constraints on models of neutrino masses and leptogenesis [PDF]
, 1998 In the supersymmetric extensions of the standard model, neutrino masses and leptogenesis requires existence of new particles. We point out that if these particles with lepton number violating interactions have standard model gauge interactions, then they

Impact of dimension-8 SMEFT operators on diboson productions
Journal of High Energy Physics, 2023 We for the first time identify all the dimension-8 (dim-8) SMEFT operators that can have an interference with the SM with E 4/Λ4 enhancement in the high energy limit for the processes q q ¯ → WW / WZ $$ q\overline{q}\to WW/ WZ $$ .

CP violation and mixing in technicolor models [PDF]
, 2004 Vacuum alignment in technicolor models provides an attractive origin for the quarks' CP violation and, possibly, a natural solution for the strong-CP problem of QCD. We discuss these topics in this paper.

Nonlinear Realization of Spontaneously Broken N=1 Supersymmetry Revisited
, 2010 This paper revisits the nonlinear realization of spontaneously broken N=1 supersymmetry. It is shown that the constrained superfield formalism can be reinterpreted in the language of standard realization of nonlinear supersymmetry via a new and simpler ...

Universal Imprints of a Pseudo-Nambu-Goldstone Higgs Boson
, 2018 A large class of models addressing the electroweak naturalness problem postulates the existence of new spontaneously broken global symmetries above the weak scale.
