Electromagnetic Radiation and in - Medium Effects

چکیده

The theory of thermal photon and dilepton emission from hot and dense hadronic matter, as well as from the Quark-Gluon Plasma, is reviewed in the context of extracting in-medium properties of the matter constituents. In phenomenological applications to ultrarelativistic heavy-ion collisions we focus on low transverse-momentum ”anomalies” as recently observed in photon and dilepton spectra by WA98 and CERES/NA45 at CERN-SPS energies.

The role of ferulic acid in the amelioration of kidney changes of rats exposed to electromagnetic radiation

Background: Electromagnetic radiation (EMR) is responsible for many hazardous impacts on living organisms. We aimed to investigate the effects of EMR on kidney tissue in rats in order to predict possible effects on human kidneys and to study the radioprotective effect of ferulic acid (FA). Materials and Methods: Six rats were used as controls, six rats were used as treated group with FA, six ra...

Investigation of Charged Particles Radiation Moving in a Homogeneous Dispersive Medium (TECHNICAL NOTE)

In this work, we use Drude-Lorents model description to study the radiation of a charged particles moving in a homogeneous dispersive medium. A suitable quantized electromagnetic field for such medium is utilized to obtain proper equations for energy loss of the particle per unit length. The energy loss is separately calculated for transverse and longitudinal components of the filed operators. ...
