Identification of the slow conversion electrons
2011/7/21
We performed at ISOLDE the spectroscopy of the decay of the 8- isomer in 136Cs by and conversion-electron detection. For the first time the excitation energy of the isomer and the multipolarity of its...
On critical scaling at the QCD N_f=2 chiral phase transition
chiral phase transition critical scaling at the QCD N_f=2
2011/7/21
We investigate the critical scaling of the quark propagator of N_f=2 QCD close to the chiral phase transition at finite temperature. We argue that it is mandatory to take into account the back-reactio...

We deduce approximate equations of state from experimental measurements in proton-proton and proton-antiproton collisions.
Non-Perturbative Prediction of the Ferromagnetic Transition in Repulsive Fermi Gases
Fermi Gases Ferromagnetic Transition
2011/7/21
It is generally believed that a dilute spin-1/2 Fermi gas with repulsive interactions can undergo a ferromagnetic phase transition to a spin-polarized state at a critical gas parameter $(k_{\text F}a)...
Nuclear matter and chiral phase transition at large-$N_{c}$
Institute of theoretical Physics, Johann Wolfgang Goethe University
2011/7/21
Two aspects of the QCD phase diagrams are studied in the limit of a large number of colors: at zero temperature and nonzero density the (non)existence of nuclear matter, and at zero density and nonzer...
A direct microscopic approach to transition strengths in pre-equilibrium reactions
microscopic approach to transition pre-equilibrium reactions
2011/7/20
We present a microscopic formalism that extends the traditional formulation of Williams, Ericson and Bloch and permits to obtain the transition strengths (TS) of pre-equilibrium nuclear reactions dire...

matrix elements neutrino mass mechanism
2011/7/20
Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the unc...

neutrinoless double-beta decay nuclear transition
2011/7/20
Neutrinoless double-beta decay nuclear transition matrix elements are generated by an effective two-body transition operator and it consists of Gamow-Teller like and Fermi like (also tensor) operators...
