 Searches for Beyond SM Higgs Bosons / Vidal Marono, Miguel (Louvain U.) /ATLAS and CMS Collaborations The measured Higgs boson, with a mass near 125~GeV, has properties consistent with the Standard Model. Besides the Standard Model interpretation, various possibilities for extended Higgs sectors are being considered. [...] CMS-CR-2015-255.- Geneva : CERN, 2015 - 15 p.

 Electromagnetic calorimetry at the highest energy and intensity proton-proton collider: CMS ECAL performance at LHC Run II and prospects for high luminosity LHC / Massironi, Andrea (Northeastern U.) /CMS Collaboration The electromagnetic calorimeter (ECAL) of the Compact Muon Solenoid Experiment (CMS) started operating at the Large Hadron Collider (LHC) in Spring 2015 with proton-proton collisions at 13 TeV center-of-mass energy and at a reduced bunch spacing of 25 ns. The instantaneous luminosity during LHC Run 2 is expected to exceed the levels achieved in LHC Run 1 significantly. In this talk we present new reconstruction algorithms and calibration strategies to maintain the superb performance of the CMS ECAL under these challenging conditions.

 CMS FPix sensor study for phase I upgrade / Yi, Kai (Iowa U.) /CMS Collaboration The next incarnation of the CMS forward pixel detector, to be installed at the extended year end technical stop 2016-17, will need to survive an integrated luminosity of 300\,fb$^{-1}$, with the inner radius of the active region of the disks decreasing from 6 to 4.5\,cm. The number of disks on each side will increase from two to three. [...] CMS-CR-2015-289.- Geneva : CERN, 2015 - 6 p.

 Search for new physics in the low MET monophoton channel with the CMS Detector / Orimoto, Toyoko Jennifer (Northeastern U.) /CMS Collaboration With the recent discovery of the Higgs boson at the Large Hadron Collider (LHC), the goals of the Compact Muon Solenoid (CMS) experiment are now focused on probing for new physics beyond the standard model. The final state consisting of a low transverse energy photon and low missing transverse energy ($E_{\mathrm{T}}^{\text{miss}}$), also called the monophoton final state, can be used to constrain a variety of extensions of the standard model, including supersymmetry.

 Quarkonia results in heavy-ion collisions from CMS / Kumar, Vineet (Bhabha Atomic Res. Ctr.) /CMS Collaboration In this talk results from CMS measurements of quarkonia in pPb and PbPb collisions will be presented. CMS has excellent muon detection capabilities which has resulted in a wealth of results on quarkonia (both charmonia as well as bottomonia) measured in dimuon channel.

 Inclusive Jet cross section and strong coupling constant measurements at CMS / Cerci, Salim (Cukurova U.) /CMS Collaboration The probes which are abundantly produced in high energetic proton-proton ($pp$) collisions at the LHC are called jets. Events with jets can be described by Quantum Chromodynamics (QCD) in terms of parton-parton scattering. [...] CMS-CR-2015-260.- Geneva : CERN, 2015 - 5 p.
