We report extensive numerical simulations of a simple model for charged colloidal particles in suspension with small nonadsorbing polymers. The chosen effective one-component interaction potential is composed of a short-range attractive part complemented by a Yukawa repulsive tail. We focus on the case where the screening length is comparable to the particle radius. Under these conditions, at l...

Within the framework of Nikiforov-Uvarov method, we obtained an approximate solution Schrodinger equation for Energy Dependent Generalized inverse quadratic Yukawa potential model. The bound state energy eigenvalues were computed various vibrational and rotational quantum numbers. Special cases considered when parameters altered, resulting into Kratzer potential, fues Inverse Potential, (screen...

The scaling behavior and fixed points in the evolution of fermion Yukawa couplings and mixing angles are discussed. The relevance of fixed points in determining the top quark mass is described. The unification of gauge couplings is a well-known feature of unified theories. To understand the masses of the observed fermions requires ideas beyond the standard model. With certain assumptions about ...

A simple analytical approach to estimate thermodynamic properties of model Yukawa systems is presented. The approach extends the traditional Debye-Hückel theory into the regime of moderate coupling and is able to qualitatively reproduce thermodynamics of Yukawa systems up to the fluid-solid phase transition. The simplistic equation of state (pressure equation) is derived and applied to the hydr...

We consider orbifold GUTs with N = 1 supersymmetry in which the Standard Model (SM) gauge couplings are unified at MGUT ≃ 2×1016 GeV with one of the third family (charged) Yukawa couplings. With split supersymmetry the SM Higgs mass is estimated to be 131±10 GeV for gauge-top quark Yukawa unification, which increases to 146± 8 GeV for gauge-bottom quark (or gauge-tau lepton) Yukawa unification....

The scaling behavior of gauge couplings and fermion Yukawa couplings in the minimal supersymmetric model is discussed. The relevance of the top quark Yukawa coupling fixed point in establishing the top quark mass is described. The evolution of mixing angles is presented. 1. Gauge Coupling Evolution The oneand two-loop renormalization group equations (RGEs) can be written for general Yukawa matr...

Unification of GUT-scale t− b− τ Yukawa couplings is a significant feature of simple SO(10) SUSY GUTs. Here we present the results of a search that used the Markov Chain Monte Carlo technique to investigate regions of Yukawa unification and WMAP-compatible dark matter relic density in SO(10)-like MSSM parameter spaces. We mention the possible LHC signatures of Yukawa unified scenarios and discu...
