Title: Measurement of F2cc and F2bb at High Q2 using the H1 Vertex Detector at HERA
Speaker: Dr Paul Thompson (Birmingham)
Measurements are presented of the contributions of both charm
and beauty quarks to the inclusive proton structure function
F2 using data from the electron-proton
collider at HERA. The production of heavy quarks is an
important process to study perturbative quantum chromodynamics.
The charm and beauty cross sections are determined using a method based on the impact parameter, in the transverse plane, of tracks to the primary vertex, as measured by the H1 vertex detector. The results are an extension to new phase space of previous H1 charm measurements and the first ever measurement of the beauty structure function F2bb.
