Fireball Heated by Neutrinos
The fireball, the promising model of the gamma-ray burst (GRB), is an opaque radiation plasma, whose energy is significantly greater than its rest mass. We numerically simulate the evolution of the fireball heated by the neutrinoantineutrino annihilation process for the spherically symmetric case. We also derive analytical energy and momentum deposition rates via neutrino scattering with therma...
متن کاملNews: Putting a damper on nanoresonators.
The harmonic oscillator holds a special place in the history of science and technology, having an important role in the development of both classical and quantum physics. Examples include Galileo’s pendulum, resonant electrical circuits and molecular vibrations. In micro and nanomechanical systems, the prototypical harmonic oscillator is a mechanical resonator — a beam of material that oscillat...
متن کاملResonances from a Hadronic Fireball
Production of φ(1020),Λ∗(1520) and K(892) resonances at the final stage of a heavy-ion collision is considered. It is shown that original momentum distributions and abundance of resonances formed during the process of heavy ion collision may differ significantly from their measured spectra and yields. Reconstruction probability of resonances decaying inside the fireball can be strongly suppress...
متن کاملCollective dynamics of the fireball
I analyse the identified single-particle pt spectra and two-pion Bose-Einstein correlations from RHIC. They indicate a massive transverse expansion and rather short lifetime of the system. The quantitative analysis in framework of the blast-wave model yields, however, unphysical results and suggests that the model may not be applicable in description of two-particle correlations. I then discuss...
متن کاملMore on the RHIC fireball and dual black holes
We revisit the issue of the RHIC “fireball” as a dual black hole, and explain some of the details. We discuss the nature of the (black hole) information paradox as a purely field theory (gauge theory) phenomenon and how the paradox can be formulated in exactly the same way for the RHIC fireball and a black hole. We stress the differences between the black holes produced in the gravity dual and ...
