Title: Measurement of Lambda_b decay asymmetry parameter and new physics searches with isolated muons in ATLAS
Abstract:
The measurement of Lambda_b->Lambda+Jpsi decay asymmetry parameter and helicity amplitudes using 7 TeV ATLAS data will be presented. The measured values are compared with theory predictions and measurements from other experiments. In the second part of the talk, two new physics searches using isolated muons will be briefly introduced.
