Strange matter in core-collapse supernovae
I. Sagert, T. Fischer, M. Hempel +4
We discuss the possible impact of strange quark matter on the evolution of core-collapse supernovae with emphasis on low critical densities for the quark-hadron phase transition. F…
The Hypothesis of Superluminal Neutrinos: comparing OPERA with other Data
Alessandro Drago, Isabella Masina, Giuseppe Pagliara +1
The OPERA Collaboration reported evidence for muonic neutrinos traveling slightly faster than light in vacuum. While waiting further checks from the experimental community, here we…
Oscillations in the decay law: A possible quantum mechanical explanation of the anomaly in the experiment at the GSI facility
Francesco Giacosa, Giuseppe Pagliara
We study the deviations from the usual exponential decay law for quantum mechanical systems. We show that simple and physically motivated deviations from the Breit-Wigner energy di…
Non exponential decays of hadrons
Giuseppe Pagliara, Francesco Giacosa
We analyze the survival probability of unstable particles in the context of quantum field theory. After introducing the spectral function of resonances, we show that deviations fro…
Nuclear matter within a dilatation-invariant parity doublet model: the role of the tetraquark at nonzero density
Susanna Gallas, Francesco Giacosa, Giuseppe Pagliara
We investigate the role of a scalar tetraquark state for the description of nuclear matter within the parity doublet model in the mirror assignment. In the dilatation-invariant ver…
Core collapse supernovae in the QCD phase diagram
T. Fischer, D. Blaschke, M. Hempel +9
We compare two classes of hybrid equations of state with a hadron-to-quark matter phase transition in their application to core collapse supernova simulations. The first one uses t…
