Twisted reduction in large N QCD with adjoint Wilson fermions
Antonio González-Arroyo, Masanori Okawa
The twisted space-time reduced model of large QCD with various flavours of adjoint Wilson fermions is constructed applying the symmetric twist boundary conditions with flux …
Perturbative analysis of twisted volume reduced theories
Margarita Garcia Perez, Antonio Gonzalez-Arroyo, Masanori Okawa
We discuss the perturbative expansion of SU(N) Yang-Mills theories defined on a d-dimensional torus of linear size l with twisted boundary conditions, generalizing previous results…
Calculation of decay amplitudes with improved Wilson fermion
N. Ishizuka, K. I. Ishikawa, A. Ukawa +1
We present results of our trial calculation of the decay amplitudes with the improved Wilson fermion action. Calculations are carried out with gauge configurat…
Mass anomalous dimension from large N twisted volume reduction
Margarita Garcia Perez, Antonio Gonzalez-Arroyo, Liam Keegan +1
In this work we consider the SU(N) gauge theory with two Dirac fermions in the adjoint representation, in the limit of large N. Taking advantage of large N twisted volume reduction…
Lattice study on chiral dynamics of two-color six-flavors QCD
Masaaki Tomii, Masashi Hayakawa, Ken-Ichi Ishikawa +2
The electroweak symmetry breaking and origin of masses may be attributed to the breakdown of chiral symmetry due to a strong gauge dynamics. Among several candidates of such gauge…
Testing reweighting method for truncated Overlap fermions
Ken-Ichi Ishikawa
The lattice QCD simulation with the lattice chiral symmetry is very attractive, however, it is difficult to maintain the symmetry at a modest numerical computation cost. A candidat…
