Evidence for modification of $b$ quark hadronization in high-multiplicity $pp$ collisions at $\sqrt{s}=13$ TeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +999

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