The LHCb detector, with its forward rapidity coverage, can probe kinematic regions at low Bjorken-x as low as . This unique capability, combined with excellent momentum resolution, vertex reconstruction, and particle identification, enables precision measurements at low transverse momentum and forward rapidity. Studies of associated production of $\Psi(2S)$ and $\Phi$ in diffractive proton-proton collisions at the LHCb experiment will be discussed. At LHC energies, investigations of diffractive events provide valuable insights into QCD phenomena. These include understanding the characteristics of pomerons and exotic hadronic states, as well as examining low-x gluon distributions and the effects of saturation.
The study of charge asymmetries in three-body 𝐵 ± → h h h decays provides a sensitive probe of CP violation in the beauty sector. Using the first data collected during LHCb Run 3, we are performing a preliminary investigation aimed at measuring these asymmetries through fits to the invariant mass distributions of selected candidates. The upgraded detector and higher instantaneous luminosity of Run 3 are expected to improve signal-to-background separation and reduce systematic uncertainties, offering enhanced sensitivity compared to previous runs. This ongoing study will lay the groundwork for precise tests of the Standard Model and potential exploration of effects beyond it.
