SU(N) fractional instantons and the Fibonacci sequence
Jorge Dasilva Golán, Margarita García Pérez
We study, by means of numerical methods, new self-dual instanton solutions on with fractional topological charge . They are obtained…
Large simulation of the twisted reduced matrix model with an adjoint Majorana fermion
Pietro Butti, Margarita García Pérez, Antonio González-Arroyo +2
To investigate the properties of the large limit of SUSY Yang-Mills theory, we have started a study for a reduced matrix model with an adjoint Majorana fermio…
Meson spectrum in the large limit
Margarita García Pérez, Antonio González-Arroyo, Masanori Okawa
We present the result of our computation of the lowest lying meson masses for SU(N) gauge theory in the large limit (with ). The final values are given…
The meson spectrum of large N gauge theories
Margarita García Pérez, Antonio González-Arroyo, Masanori Okawa
We present our preliminary results on the determination of the low lying meson spectrum for pure gauge theory in the large limit. Some results are also shown for the theory wit…
`t Hooft model on the Lattice
Margarita García Pérez, Antonio González-Arroyo, Liam Keegan +1
Lattice results are presented for the meson spectrum of 1+1 dimensional gauge theory at large , using the Twisted Eguchi-Kawai model. Comparison is made to the results obtained…
Meson masses and decay constants at large
Margarita García Pérez, Antonio González-Arroyo, Masanori Okawa
Meson masses and decay constants in the large limit of SU() gauge theory are determined using the twisted Eguchi-Kawai reduced model. To this end, we make use of a recently…
Glueball masses in 2+1 dimensional SU(N) gauge theories with twisted boundary conditions
Margarita García Pérez, Antonio González-Arroyo, Mateusz Koren +1
We analyze 2+1 dimensional Yang-Mills theory regularized on a lattice with twisted boundary conditions in the spatial directions. In previous work it was shown that the observables…
TEK twisted gradient flow running coupling
Margarita García Pérez, Antonio González-Arroyo, Liam Keegan +1
We measure the running of the twisted gradient flow coupling in the Twisted Eguchi-Kawai (TEK) model, the SU(N) gauge theory on a single site lattice with twisted boundary conditio…
Probing the Yang-Mills vacuum with adjoint zero-modes
Margarita García Pérez, Antonio González-Arroyo, Alfonso Sastre
For the non-perturbative analysis of the topological content of Yang-Mills theories, it is essential to disentangle long-range structures from short-range fluctuations. Some time a…
Adjoint fermion zero-modes for SU(N) calorons
Margarita García Pérez, Antonio González-Arroyo, Alfonso Sastre
We derive analytic formulas for the zero-modes of the Dirac equation in the adjoint representation in the background field of Q=1 SU(N) calorons. Solutions with various boundary co…
Contribution of disconnected diagrams to the hyperfine splitting of charmonium
TARO Collaboration, Philippe de Forcrand, Margarita García Pérez +6
We discuss the contribution of OZI-suppressed diagrams to the hyperfine splitting of charmonium in lattice QCD. We study valence quark mass regions from strange to charm quark mass…
Quenched charmonium spectrum
S. Choe, Ph. de Forcrand, M. Garcia Perez +5
We study charmonium using the standard relativistic formalism in the quenched approximation, on a set of lattices with isotropic lattice spacings ranging from 0.1 to 0.04 fm. We co…
