Enhanced production of ${\Lambda }_b^0$ baryons in high-multiplicity $pp$ collisions at $\sqrt{s}=13$ TeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1085

The production rate of ${\Lambda }_b^0$ baryons relative to $B^0$ mesons in $pp$ collisions at a center-of-mass energy $\sqrt{s}=13$ TeV is measured by the LHCb experiment. The rati…
