Singularity Free Direct calculation of spontaneous mass generation 青木, 健一 80 00150912 00150912 00150912 Aoki, Kenichi 85760 00150912 Kobayashi, Tamao 78494 Kumamoto, Shin-Ichiro 78495 Onai, Shinnosuke 78496 spontaneous symmetry breakdown chiral symmetry mass generation QCD We propose a new iterative method to directly calculate the spontaneous mass generation. It is regarded as a new regularization method resembling the finite volume calculation which assures non-negative fluctuation property at every stage. We work with the Nambu–Jona-Lasinio model and the strong coupling gauge theory where the dynamical chiral symmetry breaking occurs. We are able to conclude the physical mass definitely without encountering any singularity nor recourse to any additional consideration like the free energy comparison. However in special case of the 1st order phase transition, we find that the iterative method has a chance to go wrong. departmental bulletin paper Institute of Science and Engineering, Kanazawa University 2017 VoR application/pdf The Science Reports of Kanazawa University 61 1 23 The Science Reports of Kanazawa University 2433-040X https://kanazawa-u.repo.nii.ac.jp/record/45106/files/Sci_Rep_61-1-23.pdf https://doi.org/10.24517/00051445 http://hdl.handle.net/2297/00051445 https://kanazawa-u.repo.nii.ac.jp/records/45106 eng http://scirep.w3.kanazawa-u.ac.jp/
