ABOUT PREPRINTS
The Preprints collection aims to cover as far as possible all the grey literature in particle physics and its related technologies. The collection contains something like 400,000 documents, out of which about 50% can be accessed electronically. The documents originate from a variety of institutes all over the world. The collection, currently available, starts in 1979 and it has a full coverage of the arXiv.org e-Print archive since its beginning in 1991.

Offline Reconstruction Algorithms for the CMS High Granularity Calorimeter for HL-LHC / Chen, Z ; Lange, Clemens (CERN) ; Meschi, Emilio (CERN) ; Scott, Edward John Titman (Imperial Coll., London) ; Seez, Christopher (Imperial Coll., London) /CMS Collaboration
The upgraded High Luminosity LHC, after the third Long Shutdown (LS3), will provide an instantaneous luminosity of $7.5 \times 10^{34}$ cm$^{-2}$ s$^{-1}$ (levelled), at theCollaboration price of extreme pileup of up to 200 interactions per crossing. Such extreme pileup poses significant challenges, in particular for forward calorimetry. [...]

The CMS HGCAL detector for the HL-LHC upgrade / Steen, Arnaud (Taiwan, Natl. Taiwan U.) /CMS Collaboration
The High Luminosity LHC (HL-LHC) will integrate 10 times more luminosity than the LHC, posing significant challenges for radiation tolerance and event pileup on detectors, especially for forward calorimetry, and hallmarks the issue for future colliders. As part of its HL-LHC upgrade program, the CMS collaboration is designing a High Granularity Calorimeter to replace the existing endcap calorimeters. [...]

Search for rare and exotic Higgs Boson decay modes / Tao, Junquan (Beijing, Inst. High Energy Phys.) /CMS Collaboration
The latest results in the search for rare and exotic Higgs boson decays in proton-proton collision events collected with the CMS detector at the LHC are presented. The searches are performed for several decay modes of Higgs boson including $\mathrm{H}\rightarrow{\rm X (X \rightarrow2$l$)\gamma}$ ($X= {\rm Z}, \gamma^* $ and $l={\rm e},\mu$), $\mathrm{H}\rightarrow{ \mu\mu / {\rm e}{\rm e}}$, invisible decays, lepton flavour violating decays and Higgs decay to light scalars or pseudo-scalars.

Quality control considerations for the development of the front end hybrid circuits for the CMS Outer Tracker upgrade / Gadek, Tomasz (CERN) ; Blanchot, Georges (CERN) ; Bonnaud, Julien Yves Robert (CERN) ; De Clercq, Jarne Theo (Vrije U., Brussels) ; Honma, Alan (CERN) ; Koliatos, Alexandros (Democritos Nucl. Res. Ctr.) ; Kovacs, Mark Istvan (CERN) ; Luetic, Jelena (Brussels U.)
The upgrade of the CMS Outer Tracker for the HL-LHC requires the design of new double-sensor modules. They contain two high-density front end hybrid circuits, equipped with flip-chip ASICs, passives and mechanical structures. [...]

CBC3: a CMS microstrip readout ASIC with logic for track-trigger modules at HL-LHC / Prydderch, Mark Lyndon (Rutherford) ; Braga, Davide (Rutherford) ; Bell, Stephen Jean-marc (Rutherford) ; Key-Charriere, M ; Jones, Lawrence (Rutherford) ; Auzinger, Georg (Imperial Coll., London) ; Borg, Johan (Imperial Coll., London) ; Hall, Geoffrey (Imperial Coll., London) ; Pesaresi, Mark Franco (Imperial Coll., London) ; Raymond, David Mark (Imperial Coll., London) et al.
The CBC3 is the latest version of the CMS Binary Chip ASIC for readout of the outer radial region of the upgraded CMS Tracker at HL-LHC. This 254-channel, 130nm CMOS ASIC is designed to be bump-bonded to a substrate to which sensors will be wire-bonded. [...]

Recent CMS B physics results / Polikarpov, Sergey (Moscow Phys. Eng. Inst.) /CMS Collaboration
Various recent CMS B physics results are reported, including measurement of B hadron lifetimes; observation of $\Upsilon\mathrm{(1S)}$ pair production; angular analysis of the rare decay $\mathrm{B}^0\rightarrow\mathrm{K}^{*0}\mu^{+}\mu^{-}$; search for X(5568) state. All analyses are performed using data collected by the CMS experiment at the LHC in pp collisions at $\sqrt{s}=8$\,TeV, which corresponds to an integrated luminosity of about $20\,\mathrm{fb}^{-1}$..

Commissioning of the first chambers of the CMS GE1/1 muon station / Ressegotti, Martina (INFN, Pavia ; Pavia U.)
The upgrades of the LHC planned in the next years will increase the instantaneous luminosity up to $5x10^{34}$ cm$^{-2}$s$^{-1}$ after Long Shutdown 3, a value about five times higher than the nominal one for which the CMS experiment was designed. The resulting larger rate of interactions will produce a higher pileup environment that will challenge the trigger system of the CMS experiment in its original configuration, in particular in the endcap region.

Tools for Trigger Rate Monitoring at CMS / Smith, Geoffrey (Notre Dame U.) ; Mueller, Charles (Notre Dame U.) ; Wightman, Andrew Steven (Notre Dame U.) /CMS Collaboration
In 2017, we expect the LHC to deliver an instantaneous luminosity of roughly $2.0 \times 10^{34}$~cm$^{-2}$s$^{-1}$ to the Compact Muon Solenoid (CMS) experiment, with about 60 simultaneous proton-proton collisions (pileup) per event. In these challenging conditions, it is important to be able to intelligently monitor the rate at which data are being collected (the trigger rate). [...]

A search for flavor-changing neutral current (FCNC) processes in associated production of a top quark and Higgs boson, with the Higgs boson decaying to a pair of b quarks, is presented. To experimentally probe the top-Higgs FCNC couplings, for the first time the single-top production is considered as a signal process. [...]
