Classical Statistical simulation of Quantum Field Theory
Takayuki Hirayama
We propose a procedure of computing the n-point function in perturbation theory of the quantum field theory as the average over the complex Gaussian noises in a classical theory. T…
Flavor Symmetry and Galois Group of Elliptic Curves
Chuichiro Hattori, Mamoru Matsunaga, Takeo Matsuoka +1
A new approach to the generation structure of fermions is proposed. We consider a brane configuration in which the brane intersection yields a two-torus in the extra space. It is a…
Lorentz Invariance And Unitarity Problem In Non-Commutative Field Theory
Katsusada Morita, Yoshitaka Okumura, Eizou Umezawa
It is shown that the one-loop two-point amplitude in {\it Lorentz-invariant} non-commutative (NC) theory is finite after subtraction in the commutative limit and satisfies th…
A Field-Theoretic Approach to Connes' Gauge Theory on
Hiromi Kase, Katsusada Morita, Yoshitaka Okumura
Connes' gauge theory on is reformulated in the Lagrangian level. It is pointed out that the field strength in Connes' gauge theory is not unique. We explicitly cons…
Lagrangian Formulation of Connes' Gauge Theory
Hiromi Kase, Katsusada Morita, Yoshitaka Okumura
It is shown that Connes' generalized gauge field in non-commutative geometry is derived by simply requiring that Dirac lagrangian be invariant under local transformations of the un…
Gauge Theories Coupled to Fermions in Generation
Hiromi Kase, Katsusada Morita, Yoshitaka Okumura
Gauge theories coupled to fermions in generation are reformulated in a modified version of extended differential geometry with the symbol . After discussing several toy models,…
