چکیده
We discuss the Higgs boson mass sum rules in the Minimal Super-symmetric Standard Model in order to estimate the upper limits on the masses of stop quarks as well as the lower bounds on the masses of the scalar Higgs boson states. The investigation of the bounds on the scale of quark-lepton compositeness derived from the CDF Collaboration (Fermilab Tevatron) data and applied to new extra gauge bosons is taken into account. These extra gauge bosons are considered in the framework of the extended SU (2) h × SU (2) l interaction model. 1. In recent years, there are interesting discussions that the answer to the question of why the top quark is so heavy could be due to extra gauge interactions that single out the fermions of the third generation. In the simplest version of many extensions of the Standard Model (SM), for example, the extension of SU(2) gauge group to SU(2) × SU(2) one [1-4], the massive SU(2) extra gauge bosons (corresponding to the broken generators) could couple to fermions in different generations with different strengths.

The Fermilab Tevatron’s operation for fixed-target physics from its start in 1983 until the end of fixed-target running in 2000 was marked by extraordinary productivity and variety. Some of the changing theoretical issues associated with this program are reviewed.

The strategies recently developed to study Higgs boson properties at the LHC are reviewed. It is shown how to obtain model-independent determinations of couplings to fermions and gauge bosons by exploiting different production and decay channels. We consider in some detail the case of Weak Boson Fusion Higgs production with H → b ¯ b as well as the prospects for the determination of the Higgs s...

We use twistor inspired rules to compute the one-loop amplitude for a Higgs boson coupling to any number of negative helicity gluons in the large top mass limit.
