Wigner's little groups are the subgroups of the Poincare group whose transformations leave the four-momentum of a given particle invariant. For a, relativistic particle in motion the little group is a boosted rotation. On the other hand, the kinematical effect of two non-colinear Lorentz boosts is another boost preceded or followed by a rotation, which is called the Wigner rotation. It is shown that there is always a Wigner rotation for a given little group rotation. The differences between those two rotations are clearly demonstrated and some interesting physical applications are presented.

HIGHER-DERIVATIVE EFFECTIVE YANG-MILLS THEORY AND STATIC SPHERICALLY SYMMETRICAL FIELD CONFIGURATIONS BASKAL, S; DERELI, T (IOP Publishing, 1993-04-01) The variational field equations and the covariantly conserved energy-momentum tensor of a higher-derivative effective Yang-Mills theory are given. A class of static spherically symmetric gauge field configurations that follow from the Wu-Yang ansatz is considered.
Dualisation of the general scalar coset in supergravity theories Yilmaz, NT (Elsevier BV, 2003-08-04) The dualised formulation of the symmetric space sigma model is peformed for a general scalar coset G/K where G is a maximally non-compact group and K is it's maximal compact subgroup. By using the twisted self-duality condition the general form of the first-order equations are obtained. The results are applied to the example of SL(2, R)/SO(2) scalar manifold of the IIB supergravity.
Noncommutative nonlinear sigma models and integrability Kürkcüoğlu, Seçkin (American Physical Society (APS), 2008-09-01) We first review the result that the noncommutative principal chiral model has an infinite tower of conserved currents and discuss the special case of the noncommutative CP1 model in some detail. Next, we focus our attention to a submodel of the CP1 model in the noncommutative spacetime A(theta)(R2+1). By extending a generalized zero-curvature representation to A(theta)(R2+1) we discuss its integrability and construct its infinitely many conserved currents. A supersymmetric principal chiral model with and wi...
Pseudospin and spin symmetry in Dirac-Morse problem with a tensor potential AYDOĞDU, OKTAY; Sever, Ramazan (Elsevier BV, 2011-09-14) Under the conditions of the pseudospin and spin symmetry, approximate analytical solutions of the Dirac-Morse problem with Coulomb-like tensor potential are presented. The energy eigenvalue equations are found and corresponding radial wave functions are obtained in terms of confluent hypergeometric functions. The energy eigenvalues are calculated numerically in the absence and presence of the tensor potential. We also investigate the contribution of the potential parameters to the energy splitting of the ps...
General analysis of polarization phenomena in inclusive and semi-inclusive radiative decays of B mesons Pak, Namık Kemal; Rekalo, MP; Yilmaz, T (IOP Publishing, 2000-07-01) Polarization characteristics of photons produced in inclusive and semi-inclusive radiative decays of B mesons, B --> gamma + X-s, B --> gamma + h + X', are described in a general model-independent framework, using the structure function formalism.
