Search for a low-mass resonance $X\to e^+e^-$ in radiative charmed meson decays
/LHCb Collaboration
This document provides details on two figures about the search for low-mass dielectron resonance in radiative charmed meson decays a LHCb to be shown at the SEARCH conference. In particular, the process under study is the Dalitz decay $D^{\ast +}_s\to D_s^+e^+e^-$ reconstructed using data collected with the upgraded LHCb detector in 2024. [...]

Performance of the HLT1 parametrised Kalman filter
/LHCb Collaboration
This document presents two figures showcasing the performance of the \texttt{Parameterised Kalman Filter} track fitting algorithm of the first trigger stage (\hltone) of the LHCb experiment. Since the beginning of the proton-proton data-taking campaign in 2025, \hltone includes the \texttt{Parameterised Kalman Filter} for obtaining the best state estimates of tracks traversing the full LHCb detector, using information of all involved tracking subdetectors [...]

Charmless $B\to hh'$ mass distributions in 2024 data
/LHCb Collaboration
The mass distributions of $B\to h^+h'^-$ are reported, where $B$ is a $b$-hadron, $B^0$, $B_s^0$ or $\Lambda_b^0$ or their charge conjugates, and $h, h'$ are pions, kaons or protons. They are obtained from $pp$ collision data collected during 2024 under nominal \lhcb Upgrade~I luminosity conditions. [...]
