-production <strong>at</strong> <strong>LHCb</strong><br />
• The MC d<strong>at</strong>a used for this analysis<br />
is based on beam collisions <strong>of</strong> E cm =<br />
10TeV. The corresponding bb crosssection<br />
is approxim<strong>at</strong>ely 300μb. <br />
• There is an error on this, as bb cross<br />
sections <strong>at</strong> <strong>the</strong> LHC is not yet fully<br />
understood.<br />
• In 0.1fb -1 , we expect:<br />
• 3e+10 bb events<br />
• 1.2e+10 B + <br />
Cross-section as a function <strong>of</strong><br />
