A new metric improving Bayesian calibration of a multistage approach studying hadron and inclusive jet suppression

W. Fan, G. Vujanovic, S. A. Bass +52

We study parton energy-momentum exchange with the quark gluon plasma (QGP) within a multistage approach composed of in-medium DGLAP evolution at high virtuality, and (linearized) B…

Ground and excited charmonium state production in p+p collisions at sqrt(s)=200 GeV

A. Adare, S. Afanasiev, C. Aidala +444

We report on charmonium measurements [J/psi(1S), psi'(2S), and chi_c(1P)] in p+p collisions at sqrt(s)=200 GeV. We find that the fraction of J/psi coming from the feed-down decay o…
