Search for resonances decaying to photon pairs with masses between 4.9 and 19.4 GeV
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1144
A search is presented for axion-like particles (ALPs) with masses between 4.9 and 19.4 GeV decaying to a pair of photons, using proton-proton collisions collected with the LHCb det…
Search for the decay
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1160
A search for the decay is made using collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an in…
Precision measurement of the baryon lifetime
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1176
A sample of collision data, corresponding to an integrated luminosity of 5.4 fb and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of t…
First observation of the decay and search for pentaquarks in the system
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1176
The decay is observed for the first time using the data sample from proton-proton collisions recorded at a center-o…
Updated measurement of violation and polarisation in decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1169
A time-integrated angular analysis of the decay , with and $\overline{K}{}^{*}\kern-1pt(892)…
Evidence of a structure and observation of excited states in the decay
LHCb collaboration, R. Aaij, C. Abellán Beteta +959
First evidence of a structure in the invariant mass distribution is obtained from an amplitude analysis of decays. The observed s…
