The first search for the doubly heavyΩ0bcbaryon and a search for the E0bcbaryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb-1.The baryons are reconstructed via their decays toΛ+cπ-and E+cπ-.No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c2,in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/c.Upper limits are set on the ratio of theΩ0bcand E0bcproduction cross-section times the branching fraction toΛ+cπ-(E+cπ-)relative to that of theΛ0b(E0b)baryon,for different lifetime hypotheses,at 95%confidence level.The upper limits range from 0.5 x 10-4to 2.5 x 10-4for theΩ0bc→Λ+cπ-(E0bc→Λ+cπ-)decay,and from 1.4x 10-3to 6.9 x 10-3for theΩ0bc→E+cπ-(E0bc→E+cπ-)decay,depending on the considered mass and lifetime of theΩ0bc(E0bc)baryon. 展开更多

- 摘要 The first search for the doubly heavyΩ0bcbaryon and a search for the E0bcbaryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb-1.The baryons are reconstructed via their decays toΛ+cπ-and E+cπ-.No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c2,in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/c.Upper limits are set on the ratio of theΩ0bcand E0bcproduction cross-section times the branching fraction toΛ+cπ-(E+cπ-)relative to that of theΛ0b(E0b)baryon,for different lifetime hypotheses,at 95%confidence level.The upper limits range from 0.5 x 10-4to 2.5 x 10-4for theΩ0bc→Λ+cπ-(E0bc→Λ+cπ-)decay,and from 1.4x 10-3to 6.9 x 10-3for theΩ0bc→E+cπ-(E0bc→E+cπ-)decay,depending on the considered mass and lifetime of theΩ0bc(E0bc)baryon.
