Observation of new $\Xi_c^0$ baryons decaying to $\Lambda_c^+K^-$
The $\Lambda_c^+K^-$ mass spectrum is studied with a data sample of $pp$ collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 5.6 fb$^{-1}$ collected by the LHCb experiment. [...]

The production of isolated photons in PbPb and pp collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV
The transverse energy ($E_{\mathrm{T}}^{\gamma}$) spectra of photons isolated from other particles are measured using proton-proton (pp) and lead-lead (PbPb) collisions at the LHC at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV with integrated luminosities of 27.4 pb$^{-1}$ and 404 $\mu$b$^{-1}$ for pp and PbPb data, respectively.

Process Quality Control Strategy for the Phase-2 Upgrade of the CMS Outer Tracker and High Granularity Calorimeter / Hinger, Viktoria
Between 2025 and 2027, some essential components of the CMS (Compact Muon Solenoid) detector - most notably the tracker and the calorimeter endcap - will be upgraded to prepare for HL-LHC (High Luminosity Large Hadron Collider) conditions. [...]

Triggering long-lived particles in HL-LHC and the challenges in the first stage of the trigger system / Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Mukherjee, Swagata (Aachen, Tech. Hochsch.) ; Sengupta, Rhitaja (Bangalore, Indian Inst. Sci.) ; Solanki, Prabhat (Bangalore, Indian Inst. Sci.)
Triggering long-lived particles at the first stage of the trigger system is very crucial in LLP searches to ensure that we do not miss them at the very beginning. [...]
