Our measurement of medium induced energy loss in QGP using photon-jet events was finally submitted to arXiv:1205.0206 and for publication in Physics Letters B (PLB). This paper has been long awaited since the conception of the heavy ion program at CMS more than 12 years ago (See early CMS Note, p122). It is the first time in the heavy ion field where the medium induced energy loss can be directly studied with a fully unbiased probe (photon).

Also today our dihadron correlations paper got accepted into EPJC!
