Critical flavor number in the 2+1D Thirring model

Particle Number Conservation in Tiie Massive Thirring Model

We computed parr-production and nontrivlal three-particle scattering amphtudes of the massive Thirring model in one loop approximation. They are found to be zero. In contrast to the massless Thirring model in the massive Thirring model an explicit solution is unknown. Methods [1] useful in the massless case cannot be applied because the axial current is not conserved. Moreover the S-matrix deri...

The Gauged Thirring Model

We propose the gauged Thirring model as a natural gauge-invariant generalization of the Thirring model, four-fermion interaction of current-current type. In the strong gauge-coupling limit, the gauged Thirring model reduces to the recently proposed reformulation of the Thirring model as a gauge theory. Especially, we pay attention to the effect coming from the kinetic term for the gauge boson f...

the effect of using critical discourse analytical tools on the improvement of the learners level of critical thinking in reading comprehension

?it is of utmost priority for an experienced teacher to train the mind of the students, and enable them to think critically and correctly. the most important question here is that how to develop such a crucial ability? this study examines a new way to the development of critical thinking utilizing critical discourse analytical tools. to attain this goal, two classes of senior english la...

Gauged Thirring Model in the Heisenberg Picture

We consider the (2+1)-dimensional gauged Thirring model in the Heisenberg picture. In this context we evaluate the vacuum polarization tensor as well as the corrected gauge boson propagator and address the issues of generation of mass and dynamics for the gauge boson (in the limits of QED3 and Thirring model as a gauge theory, respectively) due to the radiative corrections.
