EPJ Web of Conferences, 2016 In this work pion and kaon condensation in the framework of chiral perturbation theory is studied. I consider a system at vanishing temperature with nonzero isospin chemical potential and strangeness chemical potential; meson masses and mixing in the ...

The width of the Δ-resonance at two loop order in baryon chiral perturbation theory
Physics Letters B, 2016 We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion–nucleon–delta and pion–delta couplings, which is relevant for the analysis of pion–nucleon ...

The Effect of the Pion-Pion Interaction on the Pion-Nucleon Scattering [PDF]
Progress of Theoretical Physics, 1961 It is suggested that the low-energy pion-nucleon p-wave shifts will be well understood by taking account of the effects of not only the pion-pion P-wave interaction but also the pion-pion S-wave interaction into the equations for the p-wave scattering amplitudes derived by Chew, Goldberger, Low, and Nambu.

The charged and neutral pion masses revisited
Physics Letters B, 2019 Results from neutrino mass and oscillation experiments now set the mass of the muon neutrino to less than 2 eV/c2. This fact, together with our former measurement of the muon momentum in pion decay at rest, pμ+=(29.79200±0.00011) MeV/c, allows us to ...

High temperature Bose-Einstein condensation
EPJ Web of Conferences, 2016 The indications of a possible pion condensation at the LHC are summarized. The condensation is predicted by the non-equilibrium hadronization model for 2.76 TeV Pb+Pb collisions at the LHC.

Sigma terms in Pion Weak-production near Threshold by Charged Current
EPJ Web of Conferences, 2012 We investigated pion production by charged weak current, which comprises vector and axial vector current. In particular, the contribution by the axial vector current is detailed at the pion threshold in terms of multipole amplitudes, which are useful ...
