ABSTRACT Carbon-chain anions were recently detected in the interstellar medium. These very reactive species are used as tracers of physical and chemical conditions a variety astrophysical environments. However, local thermodynamic equilibrium generally not fulfilled these Therefore, collisional well radiative rates needed to accurately model observed emission lines. We determine this work state...

The azimuthal asymmetry of minijet system produced at the early stage of nucleon-nucleon and nuclear collisions in a central rapidity window is studied. We show that in pp collisions the minijet transverse energy production in a central rapidity window is essentially unbalanced in azimuth due to asymmetric contributions in which only one minijet hits the acceptance window. We further study the ...
