The $W$ boson mass is measured using proton-proton collision data at $\sqrt{s}=13$ TeV corresponding to an integrated luminosity of 1.7 fb$^{-1}$ recorded during 2016 by the LHCb experiment. With a simultaneous fit muon $q/p_T$ distribution sample $W \to \mu\nu$ decays and $\phi^*$ $Z\to\mu\mu$ determined be \begin{equation*} m_{W} = 80354 \pm 23_{\rm stat} 10_{\rm exp} 17_{\rm theory} 9_{\rm P...

The effect of beam related systematics, namely uncertainty in the beam energy and differential luminosity spectrum measurements and beam energy spread on the precision of the Higgs boson mass measurement at a future linear e + e − collider is investigated. A future linear e + e − collider will be an ideal tool to measure Higgs bo-son properties. A number of studies have been performed to examin...

Higgs boson searches are commonly considered one of the main objectives of particle physics nowadays. The latest results obtained by the CDF and DØ collaborations are presented here when seatching for Higgs boson decaying into a W-boson pair, currently the most sensitive channel for masses greater than 130 GeV. The presented results are based on an integrated luminosity that ranges from 3.0 to ...

The cross section measurements of the Higgs boson production in the vector boson fusion (VBF) process at the LHC followed by a Higgs boson decay into ττ , WW and γγ will significantly extend the possibility of Higgs boson coupling measurements. Prospective analyses with the CMS experiment are discussed for the H → γγ , WW and ττ decay channels for an integrated LHC luminosity of 30 fb−1. For a ...

A weakly coupled new neutral gauge boson forms a narrow resonance that is hard to discover directly in ee collisions. However, if the gauge boson mass is below the center-of-mass energy, it can be produced through processes where the effective energy is reduced due to initial-state radiation and beamstrahlung. It is shown that at a high-luminosity linear collider, such a gauge boson can be sear...

Abstract: In this paper, we analyze the high-energy limits for Higgs boson + two jet production. We consider two high-energy limits, corresponding to two different kinematic regions: (a) the Higgs boson is centrally located in rapidity between the two jets, and very far from either jet; (b) the Higgs boson is close to one jet in rapidity, and both of these are very far from the other jet. In bo...

We show that the R-parity breaking SUSY model characterized by an effective bilinear violation of R-parity in the superpotential. The CP-odd Higgs boson mass and charged Higgs boson mass are discussed. In this model, it has new mass mixing such as τ− − κ̃i (i = 1, 2), We compute the mixing production e+e− → τκ̃i (i = 1, 2) in e+e− colliders. 12.60.Jv, 13.10.+q, 14.80.Ly Typeset using REVTEX 1

The agreement of electroweak measurements with theory places limits on the masses of the top quark and the W boson. It is shown how these limits arise and what constraints various measurements (particularly a top quark mass determination) would provide on the theory. The degree to which present and future measurements can constrain the Higgs boson mass is examined.
