Measurement of the effective leptonic weak mixing angle
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1120
Using collision data at TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of fb, the forward-…
Precision measurement of the baryon lifetime
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1067
A sample of collision data, corresponding to an integrated luminosity of 5.5 fb and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of t…
Measurement of production in Pb collisions at TeV at LHCb
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1048
A study of prompt production in proton-lead collisions is performed with the LHCb experiment at a centre-of-mass energy per nucleon pair of 8.16 TeV in 2016 in Pb a…
Tracking of charged particles with nanosecond lifetimes at LHCb
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1063
A method is presented to reconstruct charged particles with lifetimes between 10 ps and 10 ns, which considers a combination of their decay products and the partial tracks created…
The LHCb upgrade I
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1305
The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger th…
Measurement of the mass difference and relative production rate of the and baryons
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1050
The mass difference between the and baryons is measured using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated lumino…
