Inclusive Jet Cross Section in p+p Collisions at √s = 200 GeV by STAR

ORAL

Abstract

Jets - collimated sprays of particles produced in high-Q2 parton scatterings provide a direct test of perturbative QCD.

Measurements of inclusive jet spectra in p+p collisions serve as a baseline for heavy-ion studies and help constrain to the Monte Carlo event generators and parton distribution functions.

We present measurements of the inclusive jet cross section in p+p collisions at √s = 200 GeV GeV, based on the year 2012 STAR dataset. Jets were reconstructed with the anti-kt algorithm for R={0.2,0.3,0.4,0.5,0.6} within acceptance |η|<1-R. Detector effects are fully corrected using iterative Bayesian unfolding methods.

These results provide a high-precision baseline for future spin-dependent and heavy-ion jet studies at RHIC and the Electron–Ion Collider.
