Search for MSSM Higgs bosons and beyond at CMS
EPS Conference on High Energy Physics, EPS-HEP2017, Meeting locationVenice, Italy, 5 Jul 2017 - 12 Jul 20172017-07-052017-07-12 Proceedings of Science (EPS-HEP2017), 254 (2017) [10.3204/PUBDB-2017-13300]  GO

Searches for beyond the Standard Model (BSM) Higgs bosons are presented, particularly in the context of MSSM and Higgs Triplet Model, including a neutral Higgs boson decays into two tau leptons, charged Higgs bosons in decays of tau lepton and neutrino, charged Higgs bosons in decays of vector bosons, and doubly-charged Higgs boson in three and four lepton final states. The data is collected with the CMS detector at the LHC which corresponds to integrated luminosities of 2.3 and 12.9 fb$^{−1}$at center-of-mass energy of 13 TeV in 2015 and 2016, respectively. [...]

The Compact Muon Solenoid (CMS) detector is a multi-purpose detector constructed in order to study high-energy particle collisions at the Large Hadron Collider (LHC) at CERN. The all-silicon design of the tracking system of the CMS experiment provided excellent resolution for charged tracks and an efficient tagging of jets during Run 1 and Run 2 of the LHC [...]

With the LHC exceeding the nominal instantaneous luminosity, the current barrel pixel detector (BPIX) of the CMS experiment at CERN will reach its performance limits and undergo significant radiation damage. In order to improve detector performance in high luminosity conditions, the entire BPIX is replaced with an upgraded version containing an additional detection layer [...]

Associated production of $Z$ bosons and $b$-jets at the LHC in the combined $k_T$ + collinear QCD factorization approach
[DESY-17-126; arXiv:1708.07079] ddc:530
We consider the production of Z bosons associated with beauty quarks at the LHC using a combined $k_T$ + collinear QCD factorization approach, which interpolates between small x and large x physics. Our consideration is based on the off-shell gluon–gluon fusion subprocess $g^* g^* \rightarrow Z Q\bar{Q}$ at the leading order $\mathcal{O}(\alpha \alpha _s^2)$ (where the Z boson further decays into a lepton pair), calculated in the $k_T$ -factorization approach, and several subleading $\mathcal{O}(\alpha \alpha _s^2 )$ and $\mathcal{O}(\alpha \alpha _s^3 )$ subprocesses involving quark–antiquark and quark–gluon interactions, taken into account in conventional (collinear) QCD factorization. [...]

Measurement of the differential cross section for top-quark-pair production in the dilepton channel at $\sqrt{s}$ = 13 TeV with the CMS detector
[arXiv:1611.09657; SNSN-323-63]
 GO
Measurements of normalized differential top-quark-pair ($t\bar{t}$) production cross sections are performed using final states with two leptons ($e^+e^-$, $\mu^+\mu^-$, and $e^\pm\mu^\mp$) in proton-proton ($pp$) collisions at $\sqrt{s}$ = 13 TeV at the CERN LHC. The data were recorded in 2015 with the CMS detector and correspond to an integrated luminosity of 2.2 fb$^{-1}$. [...]

Towards the next generation of simplified Dark Matter models
[arXiv:1607.06680] ddc:530
This White Paper is an input to the ongoing discussion about the extension and refinement of simplified Dark Matter (DM) models. It is not intended as a comprehensive review of the discussed subjects, but instead summarises ideas and concepts arising from a brainstorming workshop that can be useful when defining the next generation of simplified DM models (SDMM).
