Introduction • With the start-up of collisions at the LHC the priority is for early physics and calibration of our detector. • Measuring the cross-sections for particles is vital in understanding the processes involved in pp interactions, and how we can use this understanding to simulate our data better. • This talk covers the first steps involved in making a measurement of B + production cross-sections (in regions of transverse momentum p T and rapidity y) at LHCb. It includes: – Plan of action – Preliminary results Mar-30-10 R. Young 2
