Profiling the CMS reconstruction options within the Calibration Loop
/CMS Collaboration
This notes presents profiling results of the CMS Prompt Calibration Loop, aiming at delivering detector conditions within 48h of data taking to promptly reconstruct the CMS data using Tier0 resources. We present the performance of an alternative reconstruction configuration, with reduced tracking iterations, in order to deliver a subset of calibration constants within an 8h target and limited computing power..

Performances of a high rate single photon trigger in Run 3
/CMS Collaboration
This note presents the performances of a new trigger requiring the presence of an isolated photon with moderate
transverse energy (ET $\approx$ 40-50 GeV) in the barrel region of the CMS detector ($\lvert\eta\rvert < 1.479$) deployed for the
2024 and 2025 data takings. The achieved threshold represents a reduction by more than a factor two with
respect to previous data takings (110 GeV), opening the acceptance for a variety of analyses, including searches
for Higgs decay into a photon and hadrons or missing transverse energy and searches relying on the presence of
a photon radiation from the initial or final state. [...]

Jet Mass Reconstruction in the CMS Phase-2 Level-1 Trigger
/CMS Collaboration
The Phase-2 upgrade of the CMS detector for the High Luminosity upgrade of the LHC (HL-LHC) includes the introduction of many new capabilities into the Level-1 trigger (L1T) subsystem. The latency will increase to $\sim$12.5 $\mu$s and the output bandwidth will increase to $\sim$750 kHz, while tracking and high-granularity calorimeter information will be available for the first time. [...]

Quality Control of the OBDT\_Theta board production for the Drift Tube Phase 2 Upgrade
/CMS Collaboration
A dedicated test setup has been prepared at the CIEMAT laboratory in Madrid to perform the quality control of the new electronics boards produced for the Phase-2 Upgrade of the CMS Drift Tubes detector.
A custom software framework was developed to select and efficiently execute a range of relevant tests, with the results analyzed and stored for future reference.
This note presents a description of the setup and some of the results obtained from the first 137 OBDT\_Theta boards tested..
