Many flavor approach to study the critical point in finite density QCD
Ryo Iwami, Shinji Ejiri, Norikazu Yamada
We discuss the QCD critical point at finite density through the study of many flavor QCD, in which two light flavors and Nf massive flavors exist. Performing simulations of QCD wit…
Exploring the nature of chiral phase transition in two-flavor QCD using extra heavy quarks
Shinji Ejiri, Ryo Iwami, Norikazu Yamada
Chiral phase transition of two flavor QCD at finite quark masses is known to be crossover except near the chiral limit, but it can turn to a first order transition when adding many…
Topology in QCD and the axion abundance
Ryuichiro Kitano, Norikazu Yamada
The temperature dependence of the topological susceptibility in QCD, chi_t, essentially determines the abundance of the QCD axion in the Universe, and is commonly estimated, based…
First order transition regions in the quark masses and chemical potential parameter space of QCD
Shinji Ejiri, Norikazu Yamada, Hiroshi Yoneyama
We investigate the phase transitions of (2+Nf)-flavor QCD, where two light flavors and Nf massive flavors exist, aiming to understand the phase structure of (2+1)-flavor QCD. Perfo…
The First Estimates of Kinematically Forbidden D Meson Decays
R. C. Verma, Norikazu Yamada, Kosuke Odagiri
The weak hadronic decay D^+ -> K^0\bar a_1^+ is kinematically forbidden at the peak mass values of the particles involved. However, occurrence of this decay has been reported with…
Renormalization group flow of linear sigma model with anomaly
Tomomi Sato, Norikazu Yamada
In the presence of finite breaking, chiral phase transition of massless two-flavor QCD is studied by tracing the renormalization group flow of the corresponding effective…
