A direct evidence of the Higgs-fermion coupling is established with the tau pair decay mode. Searches for Higgs Bosons decaying to leptons in scenarios Beyond the Standard Model such as supersymmetry...

The precise determination of the mass, couplings and other properties of the
particle discovered in 2012 around 125 GeV is important to establish precisely
if it is a Standard Model Higgs boson. CMS experiment has collected lot more
data since the discovery of this particle in July 2012 and has performed many
of its properties measurements. In this talk, I will present some of these...

A search for the Standard Model (SM) Higgs boson decaying to bottom quarks
pairs is presented. Two production channels have been analyzed: vector-boson

and 2012, at center-of-mass energies of 7 and 8 TeV, corresponding to...

Since the discovery of the Higgs boson by the ATLAS and CMS experiments
at the LHC, the emphasis has shifted towards measurements of its properties.
Of particular importance is the direct observation of the coupling of the
Higgs boson to fermions. In this presentation a comprehensive review of
ATLAS results in the search for the Higgs boson in tau, muon, and b-quark
pairs will be given.

Jet vetoes play a crucial role in the precise measurement of the Higgs properties at the LHC. The vetoes on additional jets introduce sensitivity to soft and collinear radiation and induce logarithms of the jet-veto variable that need to be resummed. In this talk, we consider Higgs production via gluon fusion with a veto on jet beam thrust, Tau_jet, which is a jet-based variable that can be...

We propose a pure four-dimensional formulation (FDF) of the d-dimensional regularization of
one-loop scattering amplitudes. In our formulation particles propagating inside the loop are rep-

One of the key topics in the physics program of the ILC is the precision measurement of the couplings of the Higgs boson.

The future precision studies of the Standard Model require excellent knowledge of the top quark mass, to an accuracy of 100 MeV or better.
