Measurement of the exclusive Υ production cross-section in pp collisions at s√=7 TeV and 8 TeV
(Springer, 2015-09-14)
A study is presented of central exclusive production of Υ(nS) states, where the Υ(nS) resonances decay to the μ + μ − final state, using pp collision data recorded by the LHCb experiment. The cross-section ...
Observation of Multiplicity Dependent Prompt χc1(3872) and ψ(2S) Production in pp Collisions
(2021-03)
The production of χc1(3872) and ψ(2S) hadrons is studied as a function of charged particle multiplicity in pp collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity ...
Transition towards a digital architecture: new conceptions on materiality and nature
(ENHSA, 2015-02)
Industrialized societies are undergoing a transition towards an informational era, in which modes of production and culture, once transformed by industrialization, are being modi½ed ...
Production of J/ψ and Υ mesons in pp collisions at s√=8 TeV
(Springer, 2013-06-14)
The production of J/ψ and Υ mesons in pp collisions at s√=8 TeV is studied with the LHCb detector. The J/ψ and Υ mesons are reconstructed in the μ + μ − decay mode and the signal yields are determined ...
Search for long-lived particles decaying to e ± μ∓ ν
(Springer, 2021-03)
Long-lived particles decaying to e±μ∓ν, with masses between 7 and 50GeV/c2 and lifetimes between 2 and 50ps, are searched for by looking at displaced vertices containing electrons and muons of opposite ...
First observation of the decay B+c → J/ψ K+
(Springer, 2013-09-13)
The decay B+c→J/ψK+ is observed for the first time using a data sample, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment in pp collisions at a centre-of-mass energy ...
Study of CP violation in B∓ → Dh∓ (h=K,π) with the modes D → K∓π±π0, D → π+π−π0 and D → K+K−π0
(American Physical Society, 2015-06-26)
An analysis of the decays of B∓→DK∓ and B∓→Dπ∓ is presented in which the D meson is reconstructed in the three-body final states K∓π±π0, π+π−π0 and K+K−π0. Using data from LHCb corresponding to an ...
First Observation of the Decay B0s→K−μ+νμ and a Measurement of |Vub|/|Vcb|
(American Physical Society, 2021-02)
The first observation of the suppressed semileptonic B0s→K−μ+νμ decay is reported. Using a data sample recorded in pp collisions in 2012 with the LHCb detector, corresponding to an integrated luminosity ...
Search for Lepton Number Violating Decays B+→π−μ+μ+ and B+→K−μ+μ+
(American Physical Society, 2012-03-07)
A search is performed for the lepton number violating decay B+→h−μ+μ+, where h− represents a K− or a π−, using an integrated luminosity of 36 pb−1 of data collected with the LHCb detector. The decay ...
Determination of fs/fd for 7 TeV pp Collisions and Measurement of the B0→D−K+ Branching Fraction
(American Physical Society, 2011-11-14)
The relative abundance of the three decay modes B0→D−K+, B0→D−π+, and B0s→D−sπ+ produced in 7 TeV pp collisions at the LHC is determined from data corresponding to an integrated luminosity of 35 pb−1. ...
