 An LHCb Vertex Locator (VELO) for 2030s / Gkougkousis, Vagelis (CERN) 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}.

For Run 3 of the LHC, LHCb will take data at an instantaneous luminosity of 2x10^33 cm^-2s^-1. [...] LHCb-PROC-2023-001; CERN-LHCb-PROC-2023-001.- Geneva : CERN, 2023 - 8.

This allows for electromagnetic dipole moment measurements, and increases the reach of undiscovered long-lived particle searches.

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.

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.

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..

The production cross-sections of$J/\psi$mesons are measured at a centre-of-mass energy of$\sqrt{s}=5$TeV.

The cross-section of coherent$J/\psi$and$\psi(2S)$in ultra-peripheral PbPb collisions is measured as a function of rapidity$y^*$and$p_{\mathrm{T}}^*\$, where the asterisk indicates that the variables are defined in the nucleus-nucleus center-of-mass frame.

 Standalone track reconstruction and matching algorithms for GPU-based High level trigger at LHCb / Jashal, Brij Kishor (Instituto de Fisica Corpuscular (IFIC), Valencia) The LHCb Upgrade in Run 3 has changed its trigger scheme for a full software selection in two steps. The first step, HLT1, will be entirely implemented on GPUs and run a fast selection aiming at reducing the visible collision rate from 30 MHz to 1 MHz.

 Fast and flexible data structures for the LHCb Run 3 software trigger / Esen, Sevda (University of Zurich (CH)) ; Hennequin, Arthur Marius (Massachusetts Inst. of Technology (US)) ; De Cian, Michel (EPFL - Ecole Polytechnique Federale Lausanne (CH)) Starting this year, the upgraded LHCb detector will collect data with a pure software trigger. In its first stage, reducing the rate from 30MHz to about 1MHz, GPUs are used to reconstruct and trigger on B and D meson topologies and high-pT objects in the event.
