First results from inclusive jet measurement with Run2 data at CMS — •Valentina Guglielmi1, Katerina Lipka1, Simone Amoroso1, Patrick Connor2, and Roman Kogler1 — 1Deutsches Elektronen-Synchrotron DESY, Notkestraße 85, D-22607 Hamburg — 2University Hamburg, Hamburg, Germany
We present preliminary results of the measurement and QCD analysis of double-differential inclusive jet cross sections in proton-proton collisions by using the full Run2 data collected by CMS experiment at a center of mass energy of s = 13 TeV. The higher accumulated luminosity, compared with the previous result, of full Run2 allows for an improved precision and opens up new corners of the phase space. This permits further testing of the Standard Model (SM) and facilitates indirect searches for physics beyond the SM. Our study addresses the high transverse momentum region, where possible contributions of new physics, e.g. different models of 4-quark contact interactions, are most significant. Furthermore, the precision of the parton distribution functions can be significantly improved and the strong coupling constant can be extracted. An overview of the current status of the measurement will be given, together with preliminary results of a simultaneous determination of alpha-s and PDFs at NNLO in QCD.
