The high luminosity and large cross section for b-quark production at the LHC makes possible the observation and study of many rare B meson decays. Recently, CMS reported on the presence of substructures in the known decay B+ → J/ψφK+. As part of that investigation, the final state B+ → ψ(2S)φK+ , with ψ(2S)→μ+μ− and φ → K+K− was also observed. We report the signal, with a significance of over...

The pixel detector is an integral part of the CMS silicon tracker, designed to measure the position and momentum of charged particles produced in high-energy collisions at the LHC (Large Hadron Collider). The LHC is the world’s largest and most powerful particle collider built at the European Organization for Nuclear Research (CERN). CMS is one of two general purpose particle detectors at the...

A search for a Standard Model-like Higgs boson decaying into the $\rm W^+W^-$ final state is performed with an integrated luminosity of 19.3$\rm fb^{-1}$ of pp collisions data recorded with the CMS detector at $\sqrt{s}$ = 8 TeV. The search is performed in the semileptonic channel in the high mass region 600 $< m_H <$ 1000 GeV, where the hadronically decaying W boson is highly boosted and its...

The CMS pixel detector is the innermost component of the all-silicon tracking system, which is the closest detector to the interaction point. The foreseen increase of the instantaneous and integrated luminosities at the LHC, during Run 2, necessitate an upgrade of the pixel detector in order to maintain the excellent tracking performance of the CMS detector. The notable new features of the...

The recent discovery of an Higgs-boson-like particle at the LHC, consistent with findings by the CDF and D\O{} collaborations at the Tevatron, completes our picture of the SM.
However, the SM does not give answers to many fundamental questions, for example how to understand the value of the electroweak scale i.e. the value of the Higgs mass within the model itself. One therefore has to test...

The forward-backward asymmetry of top quark pair production at the Tevatron experiments has been one of the hottest topics in particle physics in recent years. It provides unique precision tests of the standard model and of physics beyond the standard model. We present for the first time the latest measurement of the top forward-backward asymmetry in the dilepton final state and summarize the...
