We are trying to search b* decaying to a a top quark and a W boson in the lepton+neutrino, bjet and Wjet final state ,in proton-proton collisions at √s = 13 TeV recorded by the CMS experiment at the CERN LHC. Data corresponding to an integrated luminosity of 35.6 fb−1 are used.

A new model, called Bulk Extra Dimension model, which is is modified by the inclusion of Higgs brane from Bulk Graviton model, leads to novel phenomenology. We consider two cases based on this new model. The process is pp → W_kk →Wφ→WWW. And the main difference between these two cases is the choice of the mass of φ. Besides, the first VVV search based on Bulk Graviton model is also studied, in...

A search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ collected in proton-proton collisions at a centre-of-mass energy of $13~\mathrm{TeV}$ in 2016. One of the bosons is required to be a W boson decaying to $e\nu$ or $\mu\nu$, while the other boson is...

We search for the EWK WGamma+2Jets process predicted in RunII. In our analysis,W produced with a photon and two Jets,W boson dacays to a muon/electron and neutrino and neutrino turns into missing energy.We use MadGraph to model several backgrounds such as QCD WGamma+Jets, TTbar and so on, for fake lepton estimation and fake photon estimation, we use data-driven model.

In the last years, several B physics experiments have measured possible hints of new physics. Leptoquarks provide a simple explanation of these results. We present a possible analysis that is looking for vector leptoquarks at the CMS experiment using the Run II statistics.

I will discuss the CMS Collaboration's recently published observation of electroweak-induced W^{\pm}W^{\pm}jj production using the channels in which the W bosons decay to electrons or muons and the 36 fb^{-1} of data collected in 2016 at a center-of-mass energy of 13 TeV. The observed significance is 5.5 standard deviations, compared to an expectation of 5.7 standard deviations. Additionally,...

One of the most important aspect in every analysis is the optimisation of the event selection. The ideal selection would efficiently eliminate the background events while keeping the signal rates untouched. Since every real selection affects signal efficiencies also, this effect has to be studied and quantified. These efficiencies can be extracted directly from the simulation, but there is a...

Angular analyses of penguin B hadron decays such as B0->K* ll constitute one of the main indirect probes of new physics at LHC, due to the clean theoretical predictions and precise experimental results that can be obtained. In this report we present the most recent results of the CMS experiment on this subject, including the measurement of the P1 and P5’ angular variables in B0->K*mumu decays.

EWK ZAjj production is precisely predicted by the SM, and anomalous quartic coupling is a probe to the physics beyond SM.
ZAjj obtained first evidence of VBS process with RunI data, First 5𝜎 measurement of VBS di-boson process has been obtained in ssWW channel with 2016 data. we aim to obtain another VBS discovery with 2016 data in EWK ZAjj, and we are reaching pre-approve now.

The measurement of the differential cross section of Z boson production in association with jets (Z+jets) in proton-proton collision at the center-of-mass energy of 13 TeV will be present. The data has been recorded with the CMS detector at the LHC during the year 2015, corresponding to an integrated luminosity of 2.19 fb−1. The goal of analysis is to perform a first measurement at 13 TeV of...
