Physics of even-even superheavy nuclei with 96 < Z < 110 in the Quark-Meson-Coupling Model

J. R. Stone, K. Morita, P. A. M. Guichon +1

The Quark-Meson-Coupling (QMC) model has been applied to the study of the properties of even-even super-heavy nuclei with 96 < Z < 110, over a wide range of neutron numbers. The ai…

A Dynamical Interpretation of Connes' Unimodularity Condition in Standard Model and Majorana Neutrino

Katsusada Morita, Yoshitaka Okumura

Standard model is minimally extended using the unitary group of Connes' color-flavor algebra. In place of Connes' unimodularity condition an extra…

Noncommutative Regularization In Gauge Theories

Katsusada Morita

Gauge invariance of noncommutative (NC) regularization which, on the basis of a Lorentz-invariant NC action regarded as a `regulated' action, neither introduces auxiliary fields no…

A New Gauge-Invariant Regularization Scheme Based on Lorentz-Invariant Noncommutative Quantum Field Theory

Katsusada Morita

The IR/UV mixing in the non-commutative (NC) field theory is investigated in Carlson-Carone-Zobin (CCZ) formalism of Lorentz-invariant NC field theory provided that the fields are…

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…
