We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a W or Z boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating from Fermilab Tevatron pp collisions at √s = 1.96 TeV, correspond to integrated luminosities of up to 9.7 fb(-1). The searches are conducted for a Higgs boson with mass in the rang...
There are lots of new physics models which predict an extra neutral gauge boson, referred as Z -boson. In a certain class of these new physics models, the Z -boson has flavor-dependent couplings with the fermions in the Standard Model (SM). Based on a simple model in which couplings of the SM fermions in the third generation with the Z -boson are different from those of the corresponding fermio...
Vector-boson fusion (VBF) processes have emerged as a particularly interesting class of scattering events from which one hopes to gain insight into the dynamics of electroweak symmetry breaking. The most prominent example is Higgs boson production via VBF, which is shown in Fig. 1. This process has been studied intensively as a tool for Higgs boson discovery [1–3] and the measurement of Higgs b...
A new scalar resonance, called the radion, with couplings to fermions and bosons similar to those of the Higgs boson, is predicted in the framework of Randall-Sundrum models, proposed solutions to the hierarchy problem with one extra dimension. An important distinction between the radion and the Higgs boson is that the radion would couple directly to gluon pairs, and in particular its decay pro...
The higher bound on the mass of the Brout-Englert-Higgs scalar boson (BEH boson for brevity) arising from radiative corrections is not stable when the Standard Model is extended to include non-decoupling particles. In particular additional generations of fermions allow for a heavier scalar. We investigate how the decay branchings of scalar boson are affected by the opening of new channels. The ...

In the wake of the recent detection of gravitational wave signal GW150914, we investigate whether GW150914 could have been produced by something other than a binary black hole system. Our proposed candidate is a binary system of solitonic boson stars. The choice of solitonic boson stars is due mainly to the structural properties of their ground states, as solitonic boson stars are capable of fo...
The SU(3) simplest little Higgs model in its original framework without the so-called μ term inevitably involves a massless pseudoscalar boson η, which is problematic for b -physics and cosmological axion limit. With the μ term introduced by hand, the η boson acquires mass mη ∼ μ, which can be lighter than half the Higgs boson mass in a large portion of the parameter space. In addition, the int...
