The final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel $H\to ZZ^{*}\to\ell^+\ell^-\ell^{'+}\ell^{'-}$, where $\ell,\ell^{'}=e$ or $\mu$, are presented. These measurements were performed using $pp$…

A possible composite nature of the Higgs could be revealed at the early stage of the LHC, by analyzing the channels where the Higgs is produced from the decay of a heavy fermion. The Higgs production from a singly-produced heavy bottom, in…

Supersymmetric QCD corrections to the gluonic production and decay rate of a CP-even Higgs boson are evaluated at next-to-leading order. To this aim, we derive an effective Lagrangian for the gluon-Higgs coupling. We show that a consistent…
I discuss production and detection at the Tevatron $\pbarp$ collider of pairs of light ($\mpi = 100$--$200\,\gev$) color--singlet technipions that are expected in all nonminimal models of technicolor. Gluon fusion production rates can be as…
A search for the production of a single top quark in association with a Higgs boson is performed using the decay $\text{H} \to \text{b} \bar{\text{b}}$. The rate of this Higgs production mode is particularly sensitive to the relative sign…

LHC searches for the standard model Higgs Boson in WW or ZZ decay modes place strong constraints on the top-Higgs state predicted in many models with new dynamics preferentially affecting top quarks. Such a state couples strongly to…
Higgs production in association with three jets via gluon fusion (GF) is an important channel for the measurement of the CP-properties of the Higgs particle at the LHC. In this letter, we go beyond the heavy top effective theory…
