Highlight of top quark properties

The top quark is the heaviest known elementary particle and plays a special role in the dynamics of fundamental interactions. Since its discovery at the Tevatron, several of its properties have been measured by the Tevatron experiments (CDF and DZERO). However, thanks to its unprecedentedly large production rate at the LHC a new level of precision in these measurements has been achieved by the LHC experiments (ATLAS and CMS). The latest LHC measurements of the top quark mass, total decay width, top-antitop spin correlations, and charge asymmetry are presented in this contribution. In addition, the results from the W-boson helicity measurement are presented.

Top Quark Decay Properties

Due to the large production cross-section, many of the top quark properties can be measured very precisely at the LHC. A very few recent results, probed only through the top quark decay vertices are presented here. These results are based on proton-proton collision datasets recorded by the ATLAS and CMS experiments at sqrt(s)=7, 8 and 13 TeV. All the measurements and observed limits are consistent with the Standard Model (SM) predictions, while strong bounds on anomalous Wtb couplings are established.

Searches for Beyond the Standard Model Higgs Bosons in ppbar collisions at sqrt{s}=1.96 TeV

The recent results on various Beyond the Standard Model (BSM) Higgs boson searches performed by the DZERO experiment at the Tevatron are presented here. In particular, the Higgs bosons in supersymmetric models and fermiophobic scenario have been investigated. No significant excess over the Standard Model (SM) expectations have been observed and accordingly limits have been established on the corresponding model parameters.

SUSY Higgs Searches at DZERO, Tevatron

During Run II of the Tevatron collider, DØcollaboration has made extensive searches for the neutral MSSM Higgs bosons ($ϕ$), produced in $\rm p\bar{p}$ collisions at $\rm \sqrt{s}=1.96$ TeV. Two such analyses, addressing inclusive $ϕ$ production with $ϕ\toτ^+τ^-$, and associated $ϕb(\bar{b})$ production with $ϕ\to b\bar{b}$ are reported here. No excess of events above the background expectation has been observed in any of these analyses. The results are combined to set constraints on the MSSM parameter space.
