Observation of [Formula: see text] and [Formula: see text] decays.

Roel Aaij, +783 more
TL;DR: The decays of proton-proton collisions at the centre-of-mass energies of 7 and 8 are observed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb.
Journal ArticleDOI

First measurement of the $$C\!P$$ C P -violating phase in $${{B} ^0_{s}} \!\rightarrow {{J /\psi }} ($$ B s 0 → J / ψ ( $$\rightarrow $$ → $$e ^+e ^-$$ e + e - ) $$\phi $$ ϕ decays

Roel Aaij, +1002 more
TL;DR: In this article, a flavour-tagged time-dependent angular analysis of the LHCb collision data is presented, where the decay of the meson is reconstructed through its decay to an equilibrium pair.

TL;DR: The photo-production of mesons at low transverse momentum was studied in peripheral lead-lead collisions collected by the LHCb experiment at a centre-of-mass energy per nucleon pair of 5 TeV, corresponding to an integrated luminosity of 210 $\rm{\mu b}^{-1}$ as discussed by the authors .
