Article Synopsis
  • The study examines charged particle production in proton-lead and proton-proton collisions at a center-of-mass energy of 5 TeV, focusing on how it varies with pseudorapidity and transverse momentum.
  • It finds that charged particle production is suppressed in proton-lead collisions compared to proton-proton in the forward region, while there's an increase in the backward region for higher transverse momentum values.
  • These findings provide valuable insights into nuclear parton distribution functions (PDFs) and saturation models, especially at low parton momentum fractions down to 10^{-6}.

An amplitude analysis of flavor-untagged B_{s}^{0}→J/ψpp[over ¯] decays is performed using a sample of 797±31 decays reconstructed with the LHCb detector. The data, collected in proton-proton collisions between 2011 and 2018, correspond to an integrated luminosity of 9  fb^{-1}. Evidence for a new structure in the J/ψp and J/ψp[over ¯] systems with a mass of 4337_{-4}^{+7} _{-2}^{+2}  MeV and a width of 29_{-12}^{+26} _{-14}^{+14}  MeV is found, where the first uncertainty is statistical and the second systematic, with a significance in the range of 3.

Branching fraction and effective lifetime measurements of the rare decay B_{s}^{0}→μ^{+}μ^{-} and searches for the decays B^{0}→μ^{+}μ^{-} and B_{s}^{0}→μ^{+}μ^{-}γ are reported using proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV, corresponding to a luminosity of 9  fb^{-1}. The branching fraction B(B_{s}^{0}→μ^{+}μ^{-})=(3.09_{-0.

A new, store-and-forward, fully digitised Teledermatology (TD) pathway was designed and implemented in an urban setting for non-two-week wait routine patients. In total 8,352 new patients had a TD consultation over 37 months. Of these, 4,748 (56.

The branching fraction of the rare B_{s}^{0}→ϕμ^{+}μ^{-} decay is measured using data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to integrated luminosities of 1, 2, and 6  fb^{-1}, respectively. The branching fraction is reported in intervals of q^{2}, the square of the dimuon invariant mass. In the q^{2} region between 1.
