Neutral Kaons in Medium: Decoherence Effects
A. A. Andrianov, R. Tarrach, J. Taron
We consider departures from hamiltonian dynamics in the evolution of neutral kaons due to their interactions with environment that generate entanglement among them. We propose a ph…
Effective Quark Models in QCD at low and intermediate energies
A. A. Andrianov, V. A. Andrianov, D. Espriu +1
The effective quark models are employed to describe the hadronization of QCD in the quark sector. They reveal a different structure depending on how the spontaneous chiral symmetry…
The Extended Chiral Quark Model confronts QCD
A. A. Andrianov, D. Espriu, R. Tarrach
We discuss the truncation of low energy effective action of QCD below the chiral symmetry breaking (CSB) scale, including all operators of dimensionality less or equal to 6 which c…
The Extended Chiral Quark Model and QCD
A. A. Andrianov, D. Espriu, R. Tarrach
We consider the low energy effective action of QCD below the chiral symmetry breaking scale, including, in Wilson's spirit, all operators of dimensionality less or equal to 6 which…
Ambiguities in QED: Renormalons versus Triviality
D. Espriu, R. Tarrach
We point out that, contrary to what is believed to hold for QCD, renormalons are genuine in QED; i.e. the ambiguities which come with them do not require cancellation by hypothetic…
