A toy model for weak interaction based on condensed gauge bosons
Hiroaki Kohyama
We construct a toy model for weak interaction based on the assumption that gauge bosons form condensates. We then discuss the model predictions calculated from the effective Feynma…
Effective model based on QCD with gluon condensate
Hiroaki Kohyama
We construct the effective model based on QCD with gluon condensate. Under the assumption that the gluons are condensed with the sharp momentum peak in the momentum space, we formu…
Universal relations between nongaussian fluctuations in heavy-ion collisions
Jiunn-Wei Chen, Jian Deng, Hiroaki Kohyama +1
We show that universality near a critical end point implies a characteristic relation between third- and fourth-order baryon susceptibilities and , resulting in a banana…
The relation between the NJL model and QCD with condensed gluons
Hiroaki Kohyama
We try to find the relation between the three-flavor Nambu-Jona-Lasinio model and QCD based on the hypothesis that the gluon momenta are sharply condensed around the QCD scale, μ_g…
Possible interpretation on the origin of four-fermion interaction
Hiroaki Kohyama
We present a possible interpretation on the origin of the four-fermion interaction used in effective field theories. Inspired by the sharp momentum peak seen in Bose-Einstein conde…
Gauge dependence on the chiral phase transition of QCD at finite temperature in the Schwinger-Dyson equation
Hiroaki Kohyama
We study the gauge dependence on the chiral phase transition of Quantum chromodynamics at finite temperature based on the quenched Schwinger-Dyson equation. We first solve the equa…
