Status of the Bc meson excitatons search is presented in our work. We discuss the 2S Bc states first discovered by ATLAS and newly confirmed by CMS and LHCb collaborations. We review the observation prospects for the rest predicted states (B∗c, 2P

Despite the absence of experimental evidence, the weak scale supersymmetry remains as one of the best motivated and studied theoretical models beyond the Standard Model. This article summarises recent ATLAS results on inclusive searches for squarks a

Despite the absence of experimental evidence, weak scale supersymmetry remains one of the best motivated and studied Standard Model extensions. This talk summarises recent ATLAS results for searches for supersymmetric (SUSY) particles, with focus on

A set of exclusive decay of the Higgs boson into a vector meson and a dilepton pair ( h → Vl + l − , with V = ϒ, J/ψ , ϕ , and l = μ , τ ) are studied in the framework of the Standard Model. We have evaluated the decay rates, the dilepton ma

Tau leptons play an important role in the physics program at the LHC. They are used in searches for new phenomena like the Higgs boson or Supersymmetry and in electroweak measurements. Identifying hadronically decaying tau leptons with good performan

Measurements of the production of pairs of gauge bosons by the ATLAS and CMS experiments at the LHC and the CDF and D0 experiments at the Tevatron are summarized. Measured cross-sections are generally consistent with Standard Model predictions calcul

The ATLAS experiment at the Large Hadron Collider (LHC) has been able to collect 5.25 fb-1 of data in 2011. For many physics analyses both in context of the Standard Model (SM) and Beyond the Standard Model (BSM) theories such as Higgs boson searches

The first ATLAS result on a search for a high mass top pair resonance at the LHC in the subset of events where both W bosons from the top decays decay to either a final state electron or muon is presented. The analysis is performed on 1.04 fb −1 of
