Binary collisions in popovici’s photogravitational model

A grid-based binary model for coulomb collisions in plasmas

Photogravitational processes

In the linearized theory of gravity coupled to the electromagnetic field, we calculate the cross sections of two processes in which both the gravitational and electromagnetic interactions play a role. Those processes, in which a graviton is produced in the final state, are: (a) the photoproduction of graviton off electrons, and (b) the production of a photon and a graviton from e-e pair annihil...

A Model of Binary Collisions Dependence of Jet Quenching in Nuclear Collisions at Rhic

Hadronic spectra at high transverse momenta from ultrarelativistic nuclear collisions result from jets produced in the early hard partonic interactions. Most frequently, the yields are expected to scale with the number of binary nucleon-nucleon collisions. However, experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) contradict these expectations: in central Au+Au collisi...

A Model of Binary Collisions Dependence of Jet Quenching in Nuclear Collisions at Ultrarelativistic Energies

Hadronic spectra at high transverse momenta from ultrarelativistic nuclear collisions result from jets produced in the early hard partonic interactions. The yields are normally expected to scale with the number of binary nucleon-nucleon collisions. However, experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) contradict these expectations: in central Au+Au collisions the ...

Stellar collisions during binary–binary and binary–single star interactions

Physical collisions between stars occur frequently in dense star clusters, either via close encounters between two single stars, or during strong dynamical interactions involving binary stars. Here we study stellar collisions that occur during binary–single and binary–binary interactions, by performing numerical scattering experiments. Our results include cross sections, branching ratios, and s...
