 Effective-energy universality approach describing total multiplicity centrality dependence in heavy-ion collisions / Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington) ; Nath Mishra, Aditya (Mexico U., ICN) ; Sahoo, Raghunath (Indian Inst. Tech., Madras) ; Sakharov, Alexander S. (CERN ; New York U. ; Manhattan Coll., Riverdale) The recently proposed participant dissipating effective-energy approach is applied to describe the dependence on centrality of the multiplicity of charged particles measured in heavy-ion collisions at the collision energies up to the highest LHC energy of 5 TeV.

 FED Firmware Interface Testing with Pixel Phase 1 Emulator / Kilpatrick, Matthew (Rice U.) /CMS Collaboration A hardware emulation of the CMS pixel detector phase 1 upgrade front-end electronics has been developed to test and validate the architecture of the back-end electronics (FED) firmware. The emulation is implemented on a Virtex 6 FPGA on the CERN GLIB uTCA platform, utilizing an 8-way SFP FPGA Mezzanine Card to drive compatible optical transmitters to the back-end electronics at \mbox{400 Mbps}.

 Construction and beam-tests of silicon-tungsten and scintillator-SiPM modules for the CMS High Granularity Calorimeter for HL-LHC / Chang, Yung-wei (Taiwan, Natl. Central U.) /CMS Collaboration A High Granularity Calorimeter (HGCAL) is being designed to replace the existing endcap calorimeters in CMS for the HL-LHC era. It features unprecedented transverse and longitudinal segmentation for both electromagnetic (ECAL) and hadronic (HCAL) compartments, with silicon sensors being chosen for the high-pseudorapidity regions due to their radiation tolerance.
