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.

A Fresh Look at the Calculation of Tunneling Actions in Multi-Field Potentials / Espinosa, J.R. (Barcelona, IFAE ; ICREA, Barcelona ; CERN) ; Konstandin, T. (DESY)
The quantum decay of a metastable vacuum is exponentially suppressed by a tunneling action that can be calculated in the semi-classical approximation as the Euclidean action of a bounce that interpolates between the false and true phases. [...]

The CMS Tracker Upgrade for the High Luminosity LHC / Delcourt, Martin (Louvain U.) /CMS Collaboration
The LHC machine is planning an upgrade program which will smoothly bring the luminosity to about $5\times10^{34}$cm$^{-2}$s$^{-1}$ in 2028, to possibly reach an integrated luminosity of 4000fb$^{-1}$ by the end of 2037. This High-Luminosity LHC scenario, HL-LHC, will require a preparation program of the LHC detectors known as Phase-2 upgrades. [...]

The upgraded front-end electronics of the CMS electromagnetic calorimeter for the HL-LHC / Cometti, Simona (INFN, Turin) /CMS Collaboration
The Compact Muon Solenoid detector was originally designed to operate for about ten years, for LHC instantaneous luminosity up to 1$\cdot$10$^{34}$ cm$^{-2}$ s$^{-1}$ and integrated luminosity of 500 fb$^{-1}$. The High Luminosity LHC will increase the instantaneous luminosity by about a factor of 5 from current levels and CMS will accumulate an integrated luminosity of 3000 fb$^{-1}$ by about 2035.With such high luminosity the electromagnetic calorimeter of CMS will have to cope with a challenging increase in number of interactions per bunch crossing and in radiation levels.The front-end readout electronics will be completely redesigned, with the goals of providing precision timing, low noise, sampling rate 4 times higher than the current one and added flexibility in the trigger system..
