On temperature dependence of quarkonium correlators
I discuss the temperature dependence of quarkonium correlators calculated in lattice QCD. I show that the dominant source of the temperature dependence comes from the zero mode contribution, while the the temperature dependence associated with melting of bound states is quite small. I study the zero mode contribution quantitatively for different quark masses and show that it is well described b...
متن کاملEqual-time temperature correlators of the one-dimensional Heisenberg XY chain
Representations as determinants of M×M dimensional matrices are obtained for equaltime temperature correlators of the anisotropic Heisenberg XY chain. These representations are simple deformations of the answers for the isotropic XX0 chain. In the thermodynamic limit, the correlators are expressed in terms of the Fredholm determinants of linear integral operators. Introduction The description o...
متن کاملOn the Temperature-Dependence of Quarkonia Correlators
Abstract. Here I review the temperature-dependence of heavy quarkonia correlators in potential models with three different screened potentials, and compare these to the results from lattice QCD. None of the potentials investigated yield results consistent with the lattice data, indicating that screening is likely not the mechanism for heavy quarkonia suppression. I also discuss a simple toy mod...
متن کاملComment on “Equal-time temperature correlators of the one-dimensional Heisenberg XY chain”, preprint solv-int/9710028
In the comment we give references to our papers where the problem was solved for more general case of time-dependent finite temperature correlators. In the recent preprint solv-int/9710028 [1] by Izergin, Kapitonov and Kitanine representations in terms of determinants of M × M matrices are obtained for equal time temperature correlators of the anisotropic XY chain. We would like to note that th...
متن کاملTemperature dependence of DNA persistence length
We have determined the temperature dependence of DNA persistence length, a, using two different methods. The first approach was based on measuring the j-factors of short DNA fragments at various temperatures. Fitting the measured j-factors by the theoretical equation allowed us to obtain the values of a for temperatures between 5°C and 42°C. The second approach was based on measuring the equili...
