Recent D0 Measurements of Forward-Backward Asymmetries for $p\overline{p}\to B^{\pm },{\Lambda }_b^0,$ and ${\Lambda }_s^0$ Production

Abstract

The Forward-Backward Asymmetries in the production of $p\overline{p}\to B^{\pm },{\Lambda }_b^0,$ and ${\Lambda }_s^0$ particles for rapidities |y| < 2 are measred by D0 for $p\overline{p}$ collisions at $\sqrt{s}$ = 1.96 TeV at the Fermilab Tevatron. $A_{FB}(B^{\pm })$ and $A_{FB}({\Lambda }_b^0)$ are consistent with zero, while $A_{FB}({\Lambda }_s^0)$ exhibits a statistically significant rise with increasing |y|.
