Study of charmonium decays to $K^0_{\rm S} K \pi$ in the $B \to (K^0_{\rm S} K \pi) K$ channels / Palano, Antimo (Universita e INFN, Bari (IT))
A study of the $B^+ \to K^0_{\rm S} K^+ K^- \pi^+ $ and $B^+ \to K^0_{\rm S} K^+ K^+ \pi^-$ decays is performed using proton-proton collisions at center-of-mass energies of 7, 8 and 13 TeV at the LHCb experiment. The $K^0_{\rm S} K^\pm \pi^\mp$ invariant mass spectra from both decay modes reveal a rich content of charmonium resonances, such as $\eta_c$, $J/\psi$, $\eta_c(2S)$ and $\chi_{c1}$. [...]

CP violation in heavy-flavour decays / Xie, Yuehong (Central China Normal University CCNU (CN))
The CKM matrix is the only source of CP violation in the Standard Model. Heavy-flavour decays provide an ideal laboratory to test the CKM mechanism. [...]

Flavour Physics at LHCb - 50 years of the KM paradigm / Koppenburg, Patrick (Nikhef National institute for subatomic physics (NL))
The LHCb experiment is in operation since 2009 and has provided measurements of the KM matrix with unprecedented precision. 50 years after the original paper we are in the position of pinning down the parameters of the theory, or possibly to show its limitations. [...]

An LHCb Vertex Locator (VELO) for 2030s / Gkougkousis, Vagelis ; Evangelos Leonidas (CERN) /LHCb Collaboration
LHCb has recently submitted a physics case for an Upgrade II detector to begin operation in 2031. The upcoming upgrade stage is designed to run at instantaneous luminosities of up to $1.5 \times 10^{34}$ $cm^{-2}s^{-1}$, and accumulate a sample of more than 300 f$^{-1}$. [...]

Real-time alignment procedure at the LHCb experiment for Run 3 / Reiss, Florian (University of Manchester (GB))
The LHCb detector at the LHC is a general purpose detector in the forward region with a focus on studying decays of c- and b-hadrons. For Run 3 of the LHC, LHCb will take data at an instantaneous luminosity of 2x10^33 cm^-2s^-1. [...]

Expanding Physics Reach with Unused Tracks in LHCb / Sanderswood, Izaac (Univ. of Valencia and CSIC (ES))
The physics reach of the LHCb detector can be extended by reconstructing particles with a long lifetime that decay in the magnet region, using only tracks from downstream of the dipole magnet. This allows for electromagnetic dipole moment measurements, and increases the reach of undiscovered long-lived particle searches. [...]

Charmless $b$-hadron decays at LHCb / Nasteva, Irina (Federal University of of Rio de Janeiro (BR)) /LHCb Collaboration
Measurements of $C\!P$ asymmetries in charmless two-body $B$-meson decays can provide stringent tests of the Standard Model. In multibody decays, short and long-distance dynamics along with a sizeable effective weak phase in the interference between tree and penguin amplitudes can lead to a rich structure of $C\!P$ violation as a function of the phase space. [...]

LHCb results in charm baryons / Xu, Jingyi (University of Chinese Academy of Sciences (CN)) /LHCb Collaboration
The LHCb experiment collected the world’s largest sample of charmed hadrons during LHC Run 1 and Run 2. With this data set, LHCb is currently providing the world’s most precise measurements of properties and production of known charmed baryons, as well as discovering many previously unobserved states.

Recent LHCb results on heavy hadron spectroscopy / Fang, Bo (Université Paris-Saclay (FR)) /LHCb Collaboration
Recent results on heavy hadron spectroscopy from the LHCb experiment are briefly introduced in these proceedings. These results contain the observation of a new excited $D^+_s$ meson in $B^0 → D^− D^+K^+ \pi^−$ decays, evidence of a new $J/\psi \Lambda$ structure in $\Xi^-_b → J/\psi \Lambda K^−$ decays, and the observation of four new resonances decaying to $J/\psi K^+$ or $J/\psi \phi$ in $B^+ → J/\psi \phi K^+$ decays..
