Impact of the QCD four-quark condensate on in-medium spectral changes of light vector mesons

S. Zschocke, O. P. Pavlenko, B. Kampfer

Within the Borel QCD sum rule approach at finite baryon density we study the role of the four-quark condensates for the modifications of the vector mesons , and in nucle…

Evaluation of QCD sum rules for HADES

S. Zschocke, B. Kampfer, O. P. Pavlenko +1

QCD sum rules are evaluated at finite nucleon densities and temperatures to determine the change of pole mass parameters for the lightest vector mesons , and in a strong…

Is there a unique thermal dilepton source in the reactions Pb(158 AGeV) + Au, Pb?

K. Gallmeister, B. Kämpfer, O. P. Pavlenko

An analysis of the dilepton measurements of the reactions Pb(158 AGeV) + Au, Pb by the CERES and NA50 collaborations points to a unique thermal source contributing to the in…

Dileptons and Charm & Bottom in Relativistic Heavy-Ion Collisions

K. Gallmeister, B. Kaempfer, O. P. Pavlenko

We study the prospects to get information about the early and hot stages of deconfined matter produced in relativistic heavy-ion collisions by analyzing dilepton and single-lepton…

Estimates of dilepton spectra from open charm and bottom decays

B. Kämpfer, O. P. Pavlenko, K. Gallmeister

The spectra of lepton pairs from correlated open charm and bottom decays in ultrarelativistic heavy-ion collisions are calculated. Our approach includes energy loss effects of the…
