On The Complete Seiberg-Witten Map For Theories With Topological Terms
L. C. Q. Vilar, O. S. Ventura, R. L. P. G. Amaral +2
The SW map problem is formulated and solved in the BRST cohomological approach. The well known ambiguities of the SW map are shown to be associated to distinct cohomological classe…
Measurement of the ppbar to ttbar production cross section at sqrt(s)=1.96 TeV in the fully hadronic decay channel
D0 Collaboration, V. Abazov
A measurement of the top quark pair production cross section in proton anti-proton collisions at an interaction energy of sqrt(s)=1.96 TeV is presented. This analysis uses 405 pb-1…
Creation of cosmological magnetic fields in a bouncing cosmology
J. M. Salim, N. Souza, S. E. Perez Bergliaffa +1
We show (in a completely analytical and exact manner) that an efficient magnetic field amplification method is operative during the bounce in a time-dependent gauge coupling model.…
Search for techniparticles in e +jets events at D0
D0 Collaboration, V. Abazov
We search for the technicolor process ppbar -> rho_T/omega_T ->W+pi_T in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb-1,…
Possibilities for charged Higgs bosons at the LHC in a SU(3)$_L\otimesU(1)_N$ Model
J. E. Cieza Montalvo, Nelson V. Cortez, J. Sá Borges +1
We have studied the branching ratios of doubly charged Higgs bosons at the LHC using a version of the SU(3)$_L\otimesU(1)_N$ electroweak model. At the end of this work we have made…
UV finiteness of 3D Yang-Mills theories with a regulating mass in the Landau gauge
D. Dudal, J. A. Gracey, R. F. Sobreiro +2
We prove that three-dimensional Yang-Mills theories in the Landau gauge supplemented with a infrared regulating, parity preserving mass term are ultraviolet finite to all orders. W…
