Towards a Gravitational Analog to S-duality in Non-abelian Gauge Theories
H. Garcia-Compean, O. Obregon, J. F. Plebanski +1
For non-abelian non-supersymmetric gauge theories, generic dual theories have been constructed. In these theories the couplings appear inverted. However, they do not possess a Yang…
The zero divisors of the Cayley-Dickson algebras over the real numbers
R. Guillermo Moreno
In this paper we describe algebraically the zero divirsors of the Cayley- Dickson algebras $\a_{n}=\erre^{2^n}$ for over the real numbers.
The Generalized Moyal Nahm and Continuous Moyal Toda Equations
Carlos Castro, Jerzy Plebanski
We present in detail a class of solutions to the Moyal Anti Self Dual Yang Mills equations that are related to of the generalized Moyal Nahm quations u…
Further remarks on isospin breaking in charmless semileptonic B decays
G. Lopez Castro, J. H. Munoz, G. Toledo Sanchez
We consider the isospin breaking corrections to charmless semileptonic decays of B mesons. Both, the recently measured branching ratios of exclusive decays by the CLEO Collaboratio…
Tests for the asymptotic behaviour of the gamma^* --> gamma pi^0 form factor
J. -M. Gerard, G. Lopez Castro
The gamma^* --> gamma pi^0 transition measured at different photon virtualities already provides us with a clean test for the behaviour of the pi^0 gamma^* gamma off-shell axial an…
One Step Non SUSY Unification
A. Pérez-Lorenzana, William A. Ponce, Arnulfo Zepeda
We show that it is possible to achieve one step gauge coupling unification in a general class of non supersymmetric models which at low energies have only the standard particle con…
