Measurement of the bottom quark production cross section using semileptonic decay electrons inpp¯collisions at √s=1.8 TeV

We present measurements of the bottom-quark production cross sections in pp{} collisions at {}s =1.8 TeV. From the inclusive electron production rate, we have determined the bottom-quark production cross sections to be 1010±{}270, 168±{}43, 37±{}10 nb for the rapidity range of {}yᵇ{}1.0 and the transverse momentum ranges of pTᵇ>15, 23, 32 GeV/c, respectively. In addition, from the associated electron-D⁰ production rate, we have determined the bottom-quark cross section to be 364±{}80(stat)±{}95(syst) nb for {}yᵇ{}1.0 and pTᵇ>19 GeV/c.
