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.

Sound speed induced production of primordial black holes / Romano, Antonio Enea (CERN ; ICRA, Pescara)
We study different mechanisms by which the speed of primordial curvature perturbations can produce an enhancement of the curvature spectrum, which could lead to the production of primordial black holes (PBH). [...]

Search for decays of the 125 GeV Higgs boson into a Z boson and a $\rho$ or $\phi$ meson
Decays of the 125 GeV Higgs boson into a Z boson and a $\rho^{0}(770)$ or $\phi(1020)$ meson are searched for using proton-proton collision data collected by the CMS experiment at the LHC at $\sqrt{s} = $ 13 TeV. [...]

The CMS Tracker Upgrade for the High Luminosity LHC / Paoletti, Simone (INFN, Florence) /CMS Collaboration
The LHC machine is planning an upgrade program which will smoothly bring the instantaneous luminosity to about $\mathrm{5 - 7.5 \times 10^{34} cm^{-2}s^{-1}}$ in 2028, to reach an integrated luminosity of $\mathrm{3000 \ fb ^{-1}}$ and possibly up to $\mathrm{4500 \ fb ^{-1}}$ by the end of 2039. This High Luminosity LHC scenario, HL-LHC, will require an upgrade program of the LHC detectors known as Phase-2 upgrade. [...]

Development of an Optical Readout Hybrid for the CMS Outer Tracker Upgrade / Rasevic, Nikola (VINCA Inst. Nucl. Sci., Belgrade) ; Blanchot, Georges (CERN) ; Baron, S ; Kovacs, Mark Istvan (CERN) ; Kulis, S ; Porret, D ; Zografos, Angelos (Natl. Tech. U., Athens)
The pixel-strip modules for the CMS Tracker Phase-2 Upgrade for the HL-LHC integrate a readout hybrid (PS-ROH) for the control and data acquisition link. This hybrid is based on the new, low power and compact gigabit transceiver (LpGBT) and the versatile transceiver VTRx+ specifically designed for the upgrade. [...]

Investigation into the event-activity dependence of $\Upsilon(\text{nS})$ relative production in proton-proton collisions at $\sqrt{s} = $ 7 TeV / CMS Collaboration
The ratios of the production cross sections between the excited $\Upsilon\text{(2S)}$ and $\Upsilon\text{(3S)}$ mesons and the $\Upsilon\text{(1S)}$ ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event. [...]
