Multicritical Points in a Lattice Yukawa Model with the Wilson - Yukawa Coupling ∗
For a lattice regularized chiral-invariant SU(2)L× SU(2)R fermion-scalar model with a Yukawa coupling y and a Wilson-Yukawa coupling w, we investigate the phase structure and in particular show the existence of the multicritical line, in the strong Yukawa and/or Wilson Yukawa coupling region, at which four phases meet. The result is in good agreement with the Monte Carlo simulation. This analyt...
متن کاملWilson–Yukawa Chiral Model on Lattice and Non-commutative Geometry
Based upon the mathematical formulas of Lattice gauge theory and non-commutative geometry differential calculus, we developed an approach of generalized gauge theory on a product of the spacetime lattice and the two discrete points(or a Z2 discrete group). We introduce a differentiation for non-nearest-neighbour points and find that this differentiation may lead to the introduction of Wilson te...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
A nuclear physicist on the lattice
Nuclear and lattice physicists share several topics of common interest, like hadronic masses, electroweak form factors and structure functions of hadrons. The main physics issues that a new collaboration between a nuclear physicist and the lattice group of the SPQcdR collaboration is going to address, are summarized and preliminary results obtained for meson and baryon masses are presented. The...
متن کاملThe phase structure of a chirally invariant lattice Higgs-Yukawa model—numerical simulations
The phase diagram of a chirally invariant lattice Higgs-Yukawa model is explored by means of numerical simulations. The results revealing a rich phase structure are compared to analytical large Nf calculations which we performed earlier. The analytical and numerical results are in excellent agreement at large values of Nf . In the opposite case the large Nf computation still gives a good qualit...
