Measurement of [Omega]0c baryon production and branching-fraction ratio BR([Omega]0c → [Omega]-e+[nu]e)/BR([Omega]0c → [Omega]-π+) in pp collisions at √s =13 TeV
The inclusive production of the charm-strange baryon Ω0c is measured for the first time via its semileptonic decay into Ω−e+𝜈e at midrapidity (|𝑦| <0.8) in proton-proton (pp) collisions at the center-of-mass energy √𝑠 =13 TeV with the ALICE detector at the LHC. The transverse momentum (𝑝T) diff...

| 520 | |a The inclusive production of the charm-strange baryon Ω0c is measured for the first time via its semileptonic decay into Ω−e+e at midrapidity (|| <0.8) in proton-proton (pp) collisions at the center-of-mass energy √ =13 TeV with the ALICE detector at the LHC. The transverse momentum (T) differential cross section multiplied by the branching ratio is presented in the interval 2 <T <12 GeV/. The branching-fraction ratio BR(Ω0c →Ω−e+e)/BR(Ω0c →Ω−+) is measured to be 1.12 ±0.22 (stat) ±0.27 (syst). Comparisons with other experimental measurements, as well as with theoretical calculations, are presented. | ||
