Dual superconformal symmetry, and the amplitude/Wilson loop connection
(Int School Advanced Studies, 2008-09-01)
We show that tree level superstring theories on certain supersymmetric backgrounds admit a symmetry which we call "fermionic T-duality". This is a non-local redefinition of the fermionic worldsheet fields similar to the ...
Current correlation functions from a bosonized theory in 3 / 2 + 1 dimensions
(Springer, 2020-02-14)
Within the context of a bosonized theory, we evaluate the current-current correlation functions corresponding to a massive Dirac field in 2 + 1 dimensions, which is constrained to a spatial half-plane. The boundary conditions ...
Física de sabores e modelos multi-Higgs
(Universidade Estadual Paulista (Unesp), 2013-02-28)
The minimal 331 model has been proposed as an extension of the Standard Model based on the gauge group SU'(3) IND. L' ?U'(1) IND.X'. In this model, the left-handed fermions transform as triplets (or anti-triplets) under ...
Search for decays of the Higgs boson into muons in P-P collisions with the CMS detector
(UniandesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2017)
"In this thesis a search for events in which the recently discovered Higgs boson decays into a pair of muons is presented. The search was performed using the data collected by the CMS experiment at CERN during Run 2 of the ...
Quadratic effective action for QED in D=2,3 dimensions
(2000-06-15)
We calculate the effective action for quantum electrodynamics (QED) in D=2,3 dimensions at the quadratic approximation in the gauge fields. We analyze the analytic structure of the corresponding nonlocal boson propagators ...
