“…Possible anomalous gluon-top quark couplings are discussed in Refs. [65][66][67][68][69][70][71]. Contact terms and new strong dynamics involving the top quark have been studied in [72][73][74][75][76][77].…”

We present a calculation of the single top quark cross section for protonantiproton interactions with √ s = 1.8 TeV at the Fermilab Tevatron collider.We examine the effects of top mass, parton distribution functions, QCD scale, and collision energy, on each of the component production mechanisms, and study the kinematic distributions for standard model electroweak production. At the upgraded Tevatron with √ s = 2.0 TeV and high luminosity, it will be possible to test the nature of the W tb coupling using single top production. We estimate the sensitivity to measure the single top cross section, and thus to directly measure V tb and the top quark partial width. We show what happens to the V tb measurement when an anomalous (V +A) component is added to the W tb coupling, and how the top quark polarization affects the kinematic distributions.14.70.

“…[8] the equivalent trilinear term explicitly violates CP. As we will see below, there is no need for any kind of explicit CP violation here, so our procedure might yield a genuine SCPV mechanism, without recurring to a CP violation coupling, any extra scalar fields, or a huge potential.…”

“…There are so many motivations that make people believe the existence of new physics in higher energy beyond SM. In Grand Unified Theory (GUT), it is reasonable to extend the non-Abelian gauge group SU (2) L into a larger non-Abelian gauge group SU (3) L [1][2][3][4][5][6][7][8][9][10][11][12], where the U (1) Y is substituted by U (1) X . The X charges of Higgs sector are critical in generating the breaking of SU (3) L gauge symmetry [13,14].…”

We consider a $$SU(3)_c \times SU(3)_L \times U(1)_X$$ S U ( 3 ) c × S U ( 3 ) L × U ( 1 ) X model from a SU(6) Grand Unified Theory (GUT). In order to explain the anomalous magnetic moments of muon and electron, we introduce two new scalar triplets without vacuum expectation values (VEVs) so that the leading contributions to $$\Delta a_{\mu }$$ Δ a μ and $$\Delta a_{e}$$ Δ a e can avoid the suppression from small muon mass. In addition, the Higgs potential stability of this 331 model is studied by giving a set of sufficient conditions to ensure the boundedness from below of the potential.
