Analysis and interpretation of new low-energy Pi-Pi scattering data
S. Descotes, N. H. Fuchs, L. Girlanda +1
The recently published E865 data on charged K_e4 decays and Pi-Pi phases are reanalyzed to extract values of the two S-wave scattering lengths, of the subthreshold parameters alpha…
Vacuum fluctuations of \bar{q}q and values of low-energy constants
S. Descotes, J. Stern
We discuss the influence of the vacuum fluctuations of \bar{q}q pairs on low-energy constants and condensates. The analysis of the Goldstone boson masses and decay constants shows…
Finite-volume analysis of N_f-induced chiral phase transitions
Sebastien Descotes, Jan Stern
In the framework of Euclidean QCD on a torus, we study the spectrum of the Dirac operator through inverse moments of its eigenvalues, averaged over topological sets of gluonic conf…
Chiral symmetry and spectrum of Euclidean Dirac operator
Sebastien Descotes
After recalling some connections between the Spontaneous Breakdown of Chiral Symmetry (SBChS) and the spectrum of the Dirac operator for Euclidean QCD on a torus, we use this tool…
Paramagnetic effect of light quark loops on Chiral Symmetry Breaking
Sebastien Descotes, Luca Girlanda, Jan Stern
We argue that light quark loops produce a paramagnetic suppression of infrared-sensitive order parameters such as <qq>, as the number N_f of light fermions increases. The possibly…
