Scaling properties of SU(2) gauge theory with mixed fundamental-adjoint action
Enrico Rinaldi, Giuseppe Lacagnina, Biagio Lucini +2
We study the phase diagram of the SU(2) lattice gauge theory with fundamental-adjoint Wilson plaquette action. We confirm the presence of a first order bulk phase transition and we…
Counting the exponents of single transfer matrices
Luca Guido Molinari, Giuseppe Lacagnina
The eigenvalue equation of a band or a block tridiagonal matrix, the tight binding model for a crystal, a molecule, or a particle in a lattice with random potential or hopping ampl…
Spectral Curves and Localization in Random Non-Hermitian Tridiagonal Matrices
L. G. Molinari, G. N. Lacagnina
Eigenvalues and eigenvectors of non-Hermitian tridiagonal periodic random matrices are studied by means of the Hatano-Nelson deformation. The deformed spectrum is annular-shaped, w…
Semileptonic form factors D to pi, K and B to pi, K from a fine lattice
A. Al-Haydari, A. Ali Khan, V. M. Braun +6
We extract the form factors relevant for semileptonic decays of D and B mesons from a relativistic computation on a fine lattice in the quenched approximation. The lattice spacing…
Matrix elements of heavy-light mesons from a fine lattice
A. Ali Khan, A. Al-Haydari, V. Braun +6
Results on semileptonic decay matrix elements of heavy-light mesons and charmonium spectrum and decay constant using a fine quenched lattice are presented.
Monopole condensation in two-flavour Adjoint QCD
G. Cossu, M. D'Elia, A. Di Giacomo +2
In QCD with adjoint fermions (aQCD) the deconfining transition takes place at a lower temperature than the chiral transition. We study the two transitions by use of the Polyakov Lo…
