Probing nuclear matter with jet conversions
We discuss the flavor of leading jet partons as a valuable probe of nuclear matter. We point out that the coupling of jets to nuclear matter naturally leads to an alteration of jet chemistry even at high transverse momentum pT . In particular, quantum chromodynamics (QCD) jets coupling to a chemically equilibrated quark gluon plasma in nuclear collisions will lead to hadron ratios at high trans...
متن کاملProbing cold dense nuclear matter.
The protons and neutrons in a nucleus can form strongly correlated nucleon pairs. Scattering experiments, in which a proton is knocked out of the nucleus with high-momentum transfer and high missing momentum, show that in carbon-12 the neutron-proton pairs are nearly 20 times as prevalent as proton-proton pairs and, by inference, neutron-neutron pairs. This difference between the types of pairs...
متن کاملProbing quark gluon plasma with jets.
We study multiple scatterings of jets on constituents of quark gluon plasma and introduce energy–energy correlations to quantify their effects. The effects from a longitudinally expanding plasma on medium as well as high energy jets are found to be significant at both RHIC and LHC energies. Because jets escape from the plasma long before the completion of mixed phase, these effects are free fro...
متن کاملProbing Lorentz Symmetry with Gravitationally Coupled Matter
The Standard Model of particle physics together with Einstein’s General Relativity provide a remarkably successful description of known phenomena. General Relativity describes gravitation at the classical level, while all other interactions are described down to the quantum level by the Standard Model. However, a single quantum-consistent theory at the Planck scale remains elusive. Ideally, exp...
متن کاملProbing the low-x structure of nuclear matter with diffractive hadron production in pA collisions
We argue that hadron production in coherent diffraction of protons on a heavy nucleus provides a very sensitive probe of the low-x QCD dynamics. This process probes the BFKL dynamics in protons and the nonlinear gluon evolution in nuclei. We calculate the diffractive hadron production cross sections in the BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) kinematic...
