Observation of an exotic narrow doubly charmed tetraquark
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994
Conventional hadronic matter consists of baryons and mesons made of three quarks and quark-antiquark pairs, respectively. The observation of a new type of hadronic state, a doubly…
Search for time-dependent violation in and decays
LHCb collaboration, R. Aaij, C. Abellán Beteta +953
A search for time-dependent violation of the charge-parity symmetry in and decays is performed at the LHCb experiment using proton-proton collis…
Measurement of the prompt-production cross-section ratio in Pb collisions at = 8.16 TeV
R. Aaij, C. Abellán Beteta, T. Ackernley +954
This Letter reports the first measurement of prompt and charmonium production in nuclear collisions at Large Hadron Collider energies. The cross-section ratio $σ(…
Precise measurement of the ratio of fragmentation fractions and of decay branching fractions
LHCb collaboration, R. Aaij, C. Abellán Beteta +955
The ratio of the and fragmentation fractions, , in proton-proton collisions at the LHC, is obtained as a function of -meson transverse momentum and collis…
Observation of new resonances decaying to and
LHCb collaboration, R. Aaij, C. Abellán Beteta +953
The first observation of exotic states with a new quark content decaying to the final state is reported with high significance from an amplitude anal…
