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,…
Quantized Axial Charge in the Hamiltonian Approach to Wilson Fermions
Tatsuya Yamaoka
We investigate the Hamiltonian formulation of 1+1~D staggered fermions and reconstruct vector and axial charge operators, found by Arkya Chatterjee et al., using the Wilson fermion…
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…
