To face the hightened requirements of real-time and precision bunch-by-bunch luminosity determination and beam-induced background monitoring at the High-Luminosity LHC, the CMS BRIL project constructs a stand-alone luminometer, the Fast Beam Condition Monitor (FBCM). It will be fully independent from the CMS central timing, trigger and data acquisition services and able to operate at all times...

The Micro-Channel Plate (MCP) is a specially crafted microporous plate with millions of independent channels, which have secondary electron emission capability. The MCP could be used as the electronic multiplier amplifier in the PMTs. There are two types of MCP Photomultiplier tube (MCP-PMT). One is the large-area electrostatic focusing PMTs (LPMT) , which always used in the large scalar...

Next-generation neutrinoless double-beta decay searches seek to elucidate the Majorana nature of neutrinos and the existence of a lepton number violating process. The LEGEND-1000 experiment represents the ton-scale phase of the LEGEND program's search for neutrinoless double-beta decay of $^{76}$Ge, following the current intermediate-stage LEGEND-200 experiment at LNGS in Italy. The...

The Fluorescence detector Array of Single-pixel Telescopes (FAST) project proposes a simplified Schmidt telescope designed for detection of ultra-high-energy cosmic rays. It maintains its optical excellence while featuring cost-effective components. The FAST prototype utilizes a segmented 1.6 m diameter mirror and four 200 mm photomultipliers at its focal plane. Currently, the first generation...

The NEXT collaboration uses a high-pressure gaseous time projection chamber with an electroluminescent amplification to search the neutrinoless double beta decay in Xe-136. The experimental program is built on solid and successful R&D, showing an excellent energy resolution (<1%) and remarkable topological discrimination. This prompts the tonne scale proposals for the technology in a phased...

We report on a novel application of computer vision techniques to extract beyond the Standard Model (BSM) parameters directly from high energy physics (HEP) flavor data. We develop a method of transforming angular and kinematic distributions into "quasi-images" that can be used to train a convolutional neural network to perform regression tasks, similar to fitting. This contrasts with the...

We report progress in using transformer models to generate particle theory Lagrangians. By treating Lagrangians as complex, rule-based constructs similar to linguistic expressions, we employ transformer architectures -proven in language processing tasks- to model and predict Lagrangians. A dedicated dataset, which includes the Standard Model and a variety of its extensions featuring various...

In view of the HL-LHC, the Phase-2 CMS upgrade will replace the entire trigger and data acquisition system. The readout electronics will be upgraded to allow a maximum L1 accept rate of 750 kHz, and a latency of 12.5 µs. The muon trigger is a multi-layer system designed to reconstruct and measure the momenta of the muons by correlating information across muon chambers on the so-called muon...

The precision measurement of daily helium fluxes with AMS during twelve years of operation in the rigidity interval from 1.71 to 100 GV is presented. The helium flux and the helium to proton flux ratio exhibit variations on multiple timescales. In nearly all the time intervals from 2014 to 2018, we observed recurrent helium flux variations with a period of 27 days. Shorter periods of 9 days...

The CMS upgrade for the High Luminosity phase of the LHC involves the installation of three GEM stations: GE1/1, GE2/1, and ME0. While GE1/1 has been operational since Run-3's onset, only two GE2/1 chambers are in place as of early 2024. ME0's installation is slated for LHC Long Shutdown 3, with GE2/1 chamber installation resuming post ME0 completion.
