Measuring nuclear modification factors at high-$p_{T}$ using jet triggers

The suppression of hadron production at high transverse momenta is one of the most important observables to study medium induced parton energy loss in ultrarelativistic heavy ion collisions. In Pb+Pb collisions at the LHC, the transverse momentum reach of this measurement can be extended to about $300$ GeV/{\it c}, due to the large hard scattering cross sections at the $\sqrt{s_{NN}}=5500$ GeV collision energy, the high luminosity and the large acceptance of the CMS tracking system ($\vert \eta \vert <2.5$). To reach this high transverse momentum range a trigger is neccessary to enhance particle yields at high $p_{T}$. In this proceedings, the benefits of a calorimeter based high jet trigger are studied with a simulation including parton energy loss and parametrized responses for the calorimeters and the resulting statistical reach of charged particle $p_{T}$ spectra for the expected nominal $0.5$ nb$^{-1}$ integrated luminosity is estimated.
