Extended supersymmetry for the Bianchi-type cosmological models
J. J. Rosales, V. I. Tkach, J. Torres
In this paper we propose a superfield description for all Bianchi-type cosmological models. The action is invariant under world-line local supersymmetry with $SU(2)_{local}XS…
"Principle of Indistinguishability" and equations of motion for particles with spin
Mauro Napsuciale
In this work we review the derivation of Dirac and Weinberg equations based on a ``principle of indistinguishability'' for the (j,0) and (0,j) irreducible representations (irreps)…
Radiative decays of light vector mesons in a quark level linear sigma model
M. Napsuciale, S. Rodriguez, E. Alvarado-Anell
We calculate the P0 to gamma gamma, V0 to P0 gamma and V0to V'0 gamma gamma decays in the framework of a U(3)xU(3) linear sigma model which includes constituent quarks. For the fir…
Around the Clock Observations of the Q0957+561 A,B Gravitationally Lensed Quasar II: Results for the second observing season
Wesley N. Colley, Rudolph E. Schild, Cristina Abajas +35
We report on an observing campaign in March 2001 to monitor the brightness of the later arriving Q0957+561 B image in order to compare with the previously published brightness obse…
Noncommutative Topological Theories of Gravity
H. Garcia-Compean, O. Obregon, C. Ramirez +1
The possibility of noncommutative topological gravity arising in the same manner as Yang-Mills theory is explored. We use the Seiberg-Witten map to construct such a theory based on…
Molecular gas in the intergalactic medium of Stephan's Quintet
Ute Lisenfeld, Stephane Leon, Jonathan Braine +3
Stephan's Quintet (SQ) is a Hickson Compact Group well known for its complex dynamical and star formation history and its rich intergalactic medium (IGM). In order to study the ext…
