Study of the Discovery Reach in Searches for Supersymmetry at CMS with 3000/fb

It is planned that the Large Hadron Collider will deliver an integrated luminosity of up to 3000$\,\text{fb}^{\text{$-$1}}$ for each experiment, requiring an upgrade of the detector which would otherwise not survive the radiation damage. The reach of several representative searches for supersymmetry with the upgraded detector is studied for this scenario, where a very high instantaneous luminosity will lead to a large number of pileup events in each bunch crossing. The studies comprise the production of gluinos decaying to third generation squarks as well as to light squarks, and the direct production of neutralino-chargino pairs decaying to final states including a Z and a W boson. Depending on the SUSY particles, we can improve the discovery reach by about 300 to 400$\,\text{GeV}$ increasing the luminosity from 300 to 3000$\,\text{fb}^{\text{$-$1}}$. In addition, the possible gain from extending the tracker up to a pseudorapidity of four is studied for vector boson fusion processes.
