Heavy-flavour tracking performance in 2024 data
/LHCb Collaboration
Heavy-flavour tracking is used to search for hits of charged heavy-flavour particles at LHCb. Its purpose is to provide additional information to improve purity in data samples of decays of these particles that have both missing momentum and vertex information in the final state [...]

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. [...]
