Deuteron electrodisintegration near threshold in the Bethe-Salpeter approach

S. G. Bondarenko, V. V. Burov, M. Beyer +1

In the framework of the covariant Bethe-Salpeter formalism we calculate the amplitude of electrodisintegration of the deuteron near the threshold energy. Due to the small relative…

Pion-pair formation and the pion dispersion relation in a hot pion gas

T. Alm, G. Chanfray, P. Schuck +1

The possibility of pion--pair formation in a hot pion gas, based on the bosonic gap equation, is pointed out and discussed in detail. The critical temperature for condensation of p…

Squeezed condensate of gluons and mass difference

D. Blaschke, H. -P. Pavel, V. N. Pervushin +2

We consider a mechanism to create the mass difference by the gluon anomaly in a squeezed vacuum. We find that the mass shift of the governing this mass difference is…

Dilepton Enhancement by Thermal Pion Annihilation in the CERES Experiment

H. -J. Schulze, D. Blaschke

We compare the recent CERES data on dielectron production in 200 GeV/u S+Au collisions with the theoretical predictions due to pion annihilation in a thermal hadronization and a st…

Variational quantum Monte Carlo ground state of GaAs

H. Eckstein, W. Schattke, M. Reigrotzki +1

Variational quantum Monte Carlo calculations are reported for the bulk GaAs semiconductor in order to present values for the ground-state energy, the lattice constant, the bulk mod…

Can we learn anything new from polarization observables of the deuteron disintegration near threshold?

S. G. Bondarenko, V. V. Burov, M. Beyer +1

We discuss polarization characteristics of the deuteron disintegration near the threshold energy. Due to the small relative energy of the outgoing pair, the dominant amplitude…

Continuum study of deconfinement at finite temperature

Axel Bender, David Blaschke, Yuri Kalinovsky +1

Deconfinement and chiral symmetry restoration are explored in a confining, renormalisable, Dyson-Schwinger equation model of two-flavour QCD. An order parameter for deconfinement i…

Effective T-odd P-even hadronic interactions from quark models

Michael Beyer

Tests of time reversal symmetry at low and medium energies may be analyzed in the framework of effective hadronic interactions. Here, we consider the quark structure of hadrons to…

Impact of medium effects on the cooling of non-superfluid and superfluid neutron stars

Ch. Schaab, D. Voskresensky, A. D. Sedrakian +2

Neutrino emission from the dense hadronic component in neutron stars is subject to strong modifications due to collective effects in the nuclear medium. We implement new estimates…

Multi-mode density matrices of light via amplitude and phase control

T. Opatrny, D. -G. Welsch, W. Vogel

A new method is described for determining the quantum state of correlated multimode radiation by interfering the modes and measuring the statistics of the superimposed fields in fo…

Homodyne detection for measuring internal quantum correlations of optical pulses

T. Opatrny, D. -G. Welsch, W. Vogel

A new method is described for determining the quantum correlations at different times in optical pulses by using balanced homodyne detection. The signal pulse and sequences of ultr…

In-medium two-nucleon properties in high electric fields

K. Morawetz, G. Röpke, Max-Planck-Gesellschaft

The quantum mechanical two - particle problem is considered in hot dense nuclear matter under the influence of a strong electric field such as the field of the residual nucleus in…

Magnetic moment of the deuteron as probe of relativistic corrections

S. G. Bondarenko, V. V. Burov, M. Beyer +1

The calculation of the magnetic moment of the deuteron in the framework of the Bethe--Salpeter approach is performed. The relativistic corrections are calculated analytically and e…

Medium modifications of the nucleon--deuteron break--up cross section in the Faddeev approach

M. Beyer, G. Röpke, A. Sedrakian

The three--nucleon scattering problem in a nuclear medium is considered within the Faddeev technique. In particular the deuteron break--up cross section that governs the formation…

J/Psi and Psi' Suppression in Hadronic Matter

K. Martins

We present a microscopic calculation of the breakup cross sections of and on pions and nucleons as a function of the kinetic energy. These cross sections are used for th…
