D mesons in a magnetic field
Philipp Gubler, Koichi Hattori, Su Houng Lee +3
We investigate the mass spectra of open heavy flavor mesons in an external constant magnetic field within QCD sum rules. Spectral ansätze on the phenomenological side are proposed…
Mesons in strong magnetic fields: (I) General analyses
Koichi Hattori, Toru Kojo, Nan Su
We study properties of neutral and charged mesons in strong magnetic fields |eB|>> Lambda_QCD^2 with Lambda_QCD being the QCD renormalization scale. Assuming long-range interaction…
Heavy Quark Diffusion in Strong Magnetic Fields at Weak Coupling and Implications for Elliptic Flow
Kenji Fukushima, Koichi Hattori, Ho-Ung Yee +1
We compute the momentum diffusion coefficients of heavy quarks, and , in a strong magnetic field along the directions parallel and perpendicular to ,…
Photon and dilepton spectra from nonlinear QED effects in supercritical magnetic fields induced by heavy-ion collisions
Koichi Hattori, Kazunori Itakura
We discuss properties of photons in extremely strong magnetic fields induced by the relativistic heavy-ion collisions. We investigate the vacuum birefringence, the real-photon deca…
QCD Kondo effect: quark matter with heavy-flavor impurities
Koichi Hattori, Kazunori Itakura, Sho Ozaki +1
We show that the Kondo effect occurs in light quark matter which contains heavy quarks as impurities. We consider a scattering between a heavy-flavor impurity and a light quark nea…
Euler-Heisenberg-Weiss action for QCD+QED
Sho Ozaki, Takashi Arai, Koichi Hattori +1
We derive an analytic expression for one-loop effective action of QCD+QED at zero and finite temperatures by using the Schwinger's proper time method. The result is a nonlinear eff…
