Mesons, PANDA and the scalar glueball
Denis Parganlija
The non-perturbative nature of Quantum Chromodynamics (QCD) at low energies has prompted the expectation that the gauge-bosons of QCD -- gluons -- might give rise to compound objec…
Superfluid two-stream instability in a microscopic model
Andreas Schmitt
The superflow in a superfluid is bounded from above by Landau's critical velocity. Within a microscopic bosonic model, I show that below this critical velocity there is a dynamical…
GSI Oscillations as Laboratory for Testing of New Physics
A. N. Ivanov, P. Kienle
We analyse recent experimental data on the GSI oscillations of the hydrogen-like heavy {^{142}}{\rm Pm}^{60+} ions that is a time modulation of the K-shell electron capture (EC) de…
Role reversal in first and second sound in a relativistic superfluid
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
Relativistic superfluidity at arbitrary temperature, chemical potential and (uniform) superflow is discussed within a self-consistent field-theoretical approach. Our starting point…
Proton Recoil Energy and Angular Distribution of Neutron Radiative Beta Decay
A. N. Ivanov, R. Hollwieser, N. I. Troitskaya +1
We analyse the proton recoil energy and angular distribution of the radiative beta-decay of the neutron to leading order in the large baryon mass expansion by taking into account t…
Deficit of reactor antineutrinos at distances smaller than 100 m and inverse beta-decay
A. N. Ivanov, R. Hollwieser, N. I. Troitskaya +3
We analyse a change of a deficit of reactor antineutrinos at distances smaller than 100 m by changing the lifetime of the neutron from tau_n = 885.7 s to tau_n = 879.6 s, calculate…
