Axion couplings in Orbifold GUTs
/ Agrawal, Prateek (UC, Santa Barbara ; Oxford U., Theor. Phys.) ; Nee, Michael (Harvard U.) ; Reig, Mario (U. Oxford (main) ; CERN)
We consider the coupling of axions to gauge bosons in higher-dimensional Grand Unified Theories (GUT) inspired by string theory constructions with D-branes on orbifold singularities, the so-called orbifold GUTs. [...]

CMS outreach overview
/ Passaseo, Marina (INFN, Padua)
/CMS Collaboration
Effective scientific communication and public outreach are essential components of modern high-energy physics research, serving to educate the public, engage stakeholders, and ensure continued support for fundamental science.
This article presents a comprehensive analysis of the communication and outreach strategies implemented by the Compact Muon Solenoid (CMS) experiment at CERN, one of the flagship experiments at the Large Hadron Collider (LHC). [...]

HGCAL detector performance and system validation with particle beams
/ Amendola, Chiara (CERN)
/CMS Collaboration
The High-Granularity Calorimeter (HGCAL) is the new endcap calorimeter of CMS for operation in the High-Luminosity LHC (HL-LHC) era. Featuring 6 million silicon pads and 280'000 scintillating tiles, for an overall area of 620\,m$^{2}$ and 370\,m$^{2}$ respectively, HGCAL will deliver precise spatial, energy, and timing measurements of particles in its active volume.
