Electroweak physics and long-lived particles at LHCb / Volle, Felicia (University of Birmingham (GB))
Extensions of the Standard Model (SM) of Particle Physics can be probed either through precision measurements of SM observables or via direct searches for processes beyond the SM (BSM). This proceeding focuses on precision measurements in the electroweak sector, in particular the properties of the $Z$ boson, $W$ boson and top quark. [...]

Machine learning in LHCb Simulation : From fast to flash / Mazurek, Michał (Liverpool U.)
Monte Carlo simulations are essential for physics analyses in high-energy physics, but their computational demands are continuously increasing. In LHCb, 90% of computing resources are used for simulations, with the calorimeter simulation being the most computationally intensive part. [...]

Bose-Einstien correlations at LHCb / Kucharczyk, Marcin (Polish Academy of Sciences (PL)) /LHCb Collaboration
LHCb detector, considered as a general purpose detector in the forward rapidity region (2 < $\eta$ < 5), has a potential to investigate the quantum interference effects at large rapidities and low transverse momenta. The results on the Bose-Einstein correlations of same-sign charged pions are summarized, being measured in proton-proton collisions at $\sqrt{s}$ = 7 TeV centre-of-mass energy and proton-lead collisions at a nucleon-nucleon centre-of-mass energy of $\sqrt{s_{NN}}$ = 5.02 TeV.

Bose-Einstein correlations in small collision systems at LHCb / Kucharczyk, Marcin (Polish Academy of Sciences (PL))
The LHCb detector, recognized as a general-purpose detector in the forward rapidity region (2 < η < 5) is capable of exploring quantum in- terference effects at high rapidities and low transverse momenta. This summary presents measurements of Bose–Einstein correlations of the same- sign charged pions studied in proton–proton collisions at √s = 7 TeV and proton–lead collisions at √sN N = 5.02 TeV, marking the first such measure- ments in the forward region at LHC energies.

LHCb Results on exotic spectroscopy / Kucharczyk, Marcin (Polish Academy of Sciences (PL)) /LHCb Collaboration
The latest years have observed a resurrection of interest in searches for exotic states motivated by precision spectroscopy studies of beauty and charm hadrons providing the observation of many new exotic states. The recent results on spectroscopy of exotic hadrons obtained by the LHCb Collaboration are reviewed. [...]

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 $\chi_{c1}$. [...]

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. [...]
