 Studies of Higgs bosons decaying to fermions with CMS / Salerno, Daniel Nicholas (Zurich U.) /CMS Collaboration This note reviews the latest results of searches for a Higgs boson decaying to fermions, including both Standard Model (SM) searches from Run I at $\sqrt{s}=8$ TeV and Run II at $\sqrt{s}=13$ TeV and di-Higgs boson production from Run II. The measurements of the Higgs boson coupling to fermions from Run I of the LHC, both in final states and initial states are also presented.. CMS-CR-2016-100.- Geneva : CERN, 2016 - 5 p.

 Search for the $H\to hh\to bb\tau\tau$ and $A\to Zh\to ll\tau\tau$ processes with 8 TeV data in CMS. / Brivio, Francesco (INFN, Milan Bicocca) /CMS Collaboration In this presentation I will report on the search for the heavy boson H decaying to a pair of 125 GeV SM-like Higgs bosons $h$ using the final state of two $\tau$ leptons and two $b$-jets and the search for a heavy boson A decaying to a SM-like Higgs boson $h$ and a $Z$ boson using the final state of two $\tau$ leptons and two leptons $\ell\ell$ ($ee$ or $\mu\mu$). The mass range considered in the analysis extends from $m_{A/H} \simeq 250$ GeV up to $m_{A/H} \simeq 350$ GeV. The analysis is performed on a dataset corresponding to an integrated luminosity $\mathcal{L} = 19.7\ fb^{-1}$ of proton-proton collision data collected in 2012 by the CMS experiment at $\sqrt{s} = 8$ TeV..

 Detector Control System for CMS RPC at GIF++ / Gul, Muhammad (Gent U.) /CMS Collaboration In the framework of the High Luminosity LHC upgrade program, the CMS muon groupbuilt several different RPC prototypes that are now under test at the new CERN Gamma Irradiation Facility (GIF++). A dedicated Detector Control System has been developed using the WinCC-OA tool to control and monitor these prototype detectors and to store the measured parameters data..

 R and D on a New Technology of Micro-pattern Gaseous Detectors Fast Timing Micro-pattern Detector / Salva Diblen, Sinem (Gent U.) /CMS Collaboration After the upgrades of the Large Hadron Collider (LHC) planned for the second and the third Long Shutdown (LS), the LHC luminosity will approach very high values. Such conditions will affect the performance of the CMS muon system, especially in the very forward region, due to the harsh expected background environment and high pile-up conditions.
