First-order Phase Transition in Three-dimensional QED with Chern--Simons Term
Kei-Ichi Kondo, Pieter Maris
We have studied the chiral phase transition in three-dimensional QED in the presence of a Chern--Simons term for the gauge field. There exists a phase where the chiral symmetry is…
Supersymmetry in Stochastic Quantization Method and Field-Dependent Kernel
Kenji Ikegami
We define a discretized Langevin equation in Stratonovich-{\it type} calculus. We show that a generating functional with a field-dependent kernel can be written in mid-point prescr…
A Parity Invariant Regularization in 3-D Quantum Electrodynamics
Tadahiko Kimura
We regularize the 3-D quantum electrodynamics by a parity invariant Pauli-Villars regularization method. We find that in the perturbation theory the Chern-Simons term is not induce…
Dynamical Breakdown of Chirality and Parity in (2+1)-dimensional QED
Kei-Ichi Kondo, Toru Ebihara, Takuya Iizuka +1
In the (2+1)-dimensional QED with and without the Chern-Simons term, we find the non-local gauge in which there is no wavefunction renormalization for the fermion in the framework…
Neutral Scalar Higgs Masses and Production Cross Sections in an Extended Supersymmetric Standard Model
Jun-ichi Kamoshita, Yasuhiro Okada, Minoru Tanaka
Upper bounds on the three neutral scalar Higgs masses are considered in the supersymmetric standard model with a gauge singlet Higgs field. When the lightest Higgs is singlet-domin…
Flavor-Dependence and Higher Orders of Gauge-Independent Solutions in Strong Coupling Gauge Theory
Kei-Ichi Kondo, Takuya Iizuka, Eiji Tanaka +1
The fermion flavor dependence of non-perturbative solutions in the strong coupling phase of the gauge theory is reexamined based on the interrelation between the inversion me…
