Taste-splitting mass and edge modes in D staggered fermions
Tatsuhiro Misumi, Tetsuya Onogi, Tatsuya Yamaoka
We investigate the symmetry structure of the D staggered fermion Hamiltonian and its implications for anomalies. Since the spin and flavor degrees of freedom of Dirac fermion…
Conserved Non-Singlet Charges for Staggered Fermion Hamiltonian in 3+1 Dimensions
Tetsuya Onogi, Tatsuya Yamaoka
We study conserved charges of the staggered fermion Hamiltonian in 3+1 dimensions. By decomposing staggered fermions into Majorana components and exploiting lattice translation sym…
Non-singlet conserved charges and anomalies in 3+1 D staggered fermions
Tetsuya Onogi, Tatsuya Yamaoka
In this paper, we show that the 3+1 D staggered fermion Hamiltonian possesses, in addition to the conserved charge that generates the vector transformation,…
Discrete symmetry and 't Hooft anomalies for 3450 model
Tetsuya Onogi, Hiroki Wada, Tatsuya Yamaoka
We report our study of the discrete symmetry for lattice 3450 model proposed by Wang and Wen. Lattice 3450 model is expected to describe the anomaly free chiral U(1) gauge theory i…
SU(6) model revisited
Tetsuya Onogi, Hiroki Wada, Tatsuya Yamaoka
We discuss the vacuum structure of the SU(6) model, a chiral gauge theory, from the perspective of anomaly matching. To this end, we first identify all possible 't Hooft anomalies…
