Constraints on the branching fraction

LHCb collaboration, R. Aaij, C. Abellán Beteta +901

A search for the decay is performed using proton-proton collision data, corresponding to an integrated luminosity of

Test of lepton universality with decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +904

The ratio of branching fractions of the decays and , , is measured for the first time using proton-p…

Observation of excited baryons in decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +959

The first observation of the decay is reported using collision data at centre-of-mass energies of 7, 8 and 13\, collected by the LHC…

Search for decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +905

Searches are performed for both prompt-like and long-lived dark photons, , produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for $A…

Model-independent study of structure in decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The only anticipated resonant contributions to decays are charmonium states in the channel. A model-independent analysis, using LHCb proton-proton colli…

Search for the lepton flavour violating decay using decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +904

A search is presented for the lepton flavour violating decay using a sample of proton--proton collisions at centre-of-mass energies of 7, 8, and 13…
