Measurement of prompt D+ and D+ s production in pPb collisions at √ sNN = 5.02 TeV

The production of prompt D+ and D-s(+) mesons is studied in proton-lead collisions at a centre-of-mass energy of root s(NN) = 5.02TeV. The data sample corresponding to an integrated luminosity of (1.58 +/- 0.02)nb(-1) is collected by the LHCb experiment at the LHC. The differential production cross-sections are measured using D+ and D-s(+) candidates with transverse momentum in the range of 0 < p(T) < 14 GeV/c and rapidities in the ranges of 1.5 < y* < 4.0 and -5.0 < y* < -2...

Observation of ᴧb0→ ᴧc+ D̄(*)0K− and ᴧb0→ ᴧc+ Ds*− decays

The decays Λb0→Λc+D¯(∗)0K- and Λb0→Λc+Ds∗- are observed for the first time, in proton-proton collision data at s=13TeV, corresponding to an integrated luminosity of 5.4fb-1 collected with the LHCb detector. Their ratios of branching fractions with respect to the Λb0→Λc+Ds- mode are measured to be (Formula presented.) where the first uncertainties are statistical, the second systematic, and the third, for the Λb0→Λc+D¯(∗)0K- decays, are due to the uncertainties on the branching fractions of th...

A spasso tra le sfaccettature odierne dell’inclusione

In questo secondo incontro con i lettori della rubrica si intende offrire una veloce panoramica dell’attuale applicazione del costrutto di inclusione ad ambiti molto differenti della vita delle persone, delle aziende, delle città. Il discorso sarà costruito su un’analisi – non sistematica – dei contenuti presentati da un’attiva e interessante rivista divulgativa del settore, che ha focalizzato il suo interesse proprio sull’inclusione e sull’innovatività che induce e provoca nella quotidianità...
