The algebra of O(3, 3) is contracted to that of E(2)-like groups in the infinite-momentum limit. It is shown through this process that there are 18 different possibilities for the representations of E(2)-like algebra if they are to be expressed in terms of Dirac gamma-matrices. It is also pointed out that the generators of this algebra are independent of the particular representation of the gamma-matrices. Possible implications of this analysis is discussed.

Eigenvalues and eigenfunctions of Woods-Saxon potential in PT-symmetric quantum mechanics
Berkdemir, Ayse; Berkdemir, Cuneyt; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2006-09-07)
Using the Nikiforov-Uvarov method which is based on solving the second-order differential equations, we firstly analyzed the energy spectra and eigenfunctions of the Woods-Saxon potential. In the framework of the PT-symmetric quantum mechanics, we secondly solved the time-independent Schrodinger equation for the PT and non-PT-symmetric version of the potential. It is shown that the discrete energy eigenvalues of the non-PT-symmetric potential consist of the real and imaginary parts, but the PT-symmetric one...
Nonlocal regularisation of noncommutative field theories
Govindarajan, T. R.; Kürkcüoğlu, Seçkin; PANERO, Marco (World Scientific Pub Co Pte Lt, 2006-08-10)
We study noncommutative field theories, which are inherently nonlocal, using a Poincare-invariant regularisation scheme which yields an effective, nonlocal theory for energies below a cutoff scale. After discussing the general features and the peculiar advantages of this regularisation scheme for theories defined in noncommutative spaces, we focus our attention on the particular case when the noncommutativity parameter is inversely proportional to the square of the cutoff, via a dimensionless parameter eta....
Dualisation of the Salam-Sugin D-8 supergravity
Dereli, T; Yilmaz, NT (Elsevier BV, 2004-07-19)
The first-order formulation of the Salam-Sezgin D = 8 supergravity coupled to N vector multiplets is discussed. The non-linear realization of the bosonic sector of the D = 8 matter coupled Salam-Sezgin supergravity is introduced by the dualisation of the fields and by constructing the Lie superalgebra of the symmetry group of the doubled field strength.

LEPTON FLAVOR VIOLATING HIGGS DECAYS AND UNPARTICLE PHYSICS
Iltan, E. O. (World Scientific Pub Co Pte Lt, 2009-06-07)
We predict the branching ratios of the lepton flavor violating Higgs decays H-0 -> e(+/-)mu(+/-), H-0 -> e(+/-)tau(+/-) and H-0 -> mu(+/-)tau(+/-) in the case that the lepton flavor violation is carried by the scalar unparticle mediation. We observe that their branching ratios are strongly sensitive to the unparticle scaling dimension and they can reach the values of the order of 10(-4), for the heavy lepton flavor case and for the small values of the scaling dimension.
Wigner rotations and little groups
Baskal, S (Springer Science and Business Media LLC, 2004-01-01)
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 rotati...
