Measuring the top-quark mass in the ttbar dilepton channel at CMS

The top-quark mass is a fundamental parameter of the standard model (SM).  
The determination of the top-quark mass is one of the precision measurements 
that provides input on the self-consistency of the SM and constraints on 
possible new physics beyond the SM.  I will present a measurement of the 
top-quark mass in the dilepton channel using the CMS 8 TeV dataset, and 
discuss techniques for mass reconstruction, non-parametric template shape 
estimation, and mitigation of systematic error coming from the overall 
uncertainty in jet energy scale determination.
