Computing strategy for PID calibration samples for LHCb Run 2 / Anderlini, Lucio (Universita e INFN, Firenze (IT)) ; Benson, Sean (Nikhef National institute for subatomic physics (NL)) ; Lupton, Olli (University of Oxford (GB)) ; Sciascia, Barbara (Istituto Nazionale Fisica Nucleare Frascati (IT)) ; Gligorov, Vladimir (Lab. Phys. Nucl. Hautes Energies (FR))
The samples for the calibration of the Particle Identification (PID) are sets of data collected by LHCb where decay candidates have a kinematic structure which allows unambiguous identification of one the daughters with a selection strategy not relying on its PID-related variables. PID calibration samples are used in a data-driven technique to measure the efficiency of selection requirements on PID variables in many LHCb analyses. [...]

Tests of the photon detection chain for the LHCb RICH Upgrade in a particle beam / Cardinale, Roberta (Universita e INFN Genova (IT))
The LHCb detector will be upgraded to use the available luminosity at the LHC in Run III and extend its potential for discovery. The Ring Imaging Cherenkov (RICH) detectors are one of the key components of the LHCb detector for particle identification. [...]

Sensitivity of LHCb and its upgrade in the measurement of $BR(K_S^0\rightarrow\pi^0\mu\mu)$ / Chobanova, Veronika Georgieva (Universidade de Santiago de Compostela (ES)) ; Cid Vidal, Xabier (Universidade de Santiago de Compostela (ES)) ; Dalseno, Jeremy Peter (University of Bristol (GB)) ; Lucio Martinez, Miriam (Universidade de Santiago de Compostela (ES)) ; Martinez Santos, Diego (Universidade de Santiago de Compostela (ES)) ; Renaudin, Victor (Laboratoire de l'Accelerateur Lineaire (FR))
The sensitivity of the LHCb experiment to $BR(K_S^0\rightarrow\pi^0\mu\mu)$ is analyzed in light of the Run-I data and the oportunities of the full software trigger of the LHCb upgrade. Two strategies are considered: the full reconstruction of the decay products and the partial reconstruction using only the dilepton pair and kinematic constraints. [...]

During the Long Shutdown 2 of the LHC, the LHCb experiment and, specifically, its two Ring Imaging Cherenkov (RICH) detectors will undergo a major upgrade. RICH 2 will be refurbished with new photon detectors and their associated electronics, with the capability of up to 40 MHz sustained acquisition rate. [...]
