Two-photon partial widths of tensor mesons
We calculate partial widths of the γγ decay of the tensor qq̄ states a2(1320), f2(1270), f2(1525), their radial excitations a2(1660), f2(1640), f2(1800) as well as F2qq̄ states. Calculations are performed in the framework of the same approach which was used before for the study of radiative decays f0(980) → γγ, a0(980) → γγ and φ(1020) → γf0(980): the assumption made is that of qq̄ structure of f0...
متن کاملAtoms at finite temperatures
These are working notes written as a first step in understanding atomic potentials and atomic structure in finite-temperature systems. 1 Thomas-Fermi Theory As a first step, we consider the Thomas-Fermi theory at finite temperatures. This is my version of the discussion of temperature-dependent Thomas-Fermi theory given in the seminal work of Feynman, Metropolis, and Teller [1]. Later, we will ...
متن کاملQuarkonium at Finite Temperatures
Quarkonium at finite temperature Takashi Umeda Brookhaven National Laboratorg, Upton, NY, USA, 11973 Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The “wave function” of charmonium is also discussed to study ...
متن کاملReduced and projected two-particle entanglement at finite temperatures.
We present a theory for two-particle entanglement production and detection in mesoscopic conductors at finite temperature. The entanglement of the density matrix projected out of the emitted many-body state differs from the entanglement of the reduced density matrix, detectable by current correlation measurements. Under general conditions reduced entanglement constitutes a witness for projected...
متن کاملTwo-particle properties in nuclear matter at finite temperatures
Correlation effects in nuclear matter at finite temperatures are studied for subnuclear densities (ρ < ρ0) and medium excitation energy, where a nonrelativistic potential approach is possible. A quantum statistical approach is given, where clusters are treated under the influence of a clustered medium treated within a mean field approximation. Spectral functions, in-medium cross sections, and r...
