Electromagnetic form factors of heavy-light pseudoscalar mesons
A. S. Miramontes, J. Papavassiliou, J. M. Pawlowski
We report calculations of space-like electromagnetic form factors and charge radii of pseudoscalar mesons, covering both light and heavy-light flavour sectors within a flavour-depe…
Cosmology from asymptotically safe Proca theories
Carlos Pastor-Marcos, Lavinia Heisenberg, Álvaro Pastor-Gutiérrez +2
Effective field theories for cosmology offer a powerful framework to investigate the dynamics of space--time and address longstanding open puzzles. In this work, we initiate a prog…
Pions reloaded
M. N. Ferreira, A. S. Miramontes, J. M. Morgado +2
We present a novel version of the pion Bethe-Salpeter equation in the chiral limit, solved using as ingredients state-of-the-art QCD correlation functions. The constraints imposed…
Pion physics with dressed quark-gluon vertices
Mauricio N. Ferreira, Angel S. Miramontes, Jose M. Morgado +2
Recently, a theoretical framework was set up in [1], which allows for the symmetry-preserving inclusion of full quark-gluon vertices in the description of the meson dynamics. In th…
Heavy-light mesons from a flavour-dependent interaction
Fei Gao, Angel S. Miramontes, Joannis Papavassiliou +1
We introduce a new symmetry-preserving framework for the physics of heavy-light mesons, whose key element is the effective incorporation of flavour-dependent contributions into the…
ADHM Construction of Instantons on the Torus
C. Ford, J. M. Pawlowski, T. Tok +1
We apply the ADHM instanton construction to SU(2) gauge theory on T^n x R^(4-n)for n=1,2,3,4. To do this we regard instantons on T^n x R^(4-n) as periodic (modulo gauge transformat…
The Two-exponential Liouville Theory and the Uniqueness of the Three-point Function
L. O'Raifeartaigh, J. M. Pawlowski, V. V. Sreedhar
It is shown that in the two-exponential version of Liouville theory the coefficients of the three-point functions of vertex operators can be determined uniquely using the translati…
Duality in Quantum Liouville Theory
L. O'Raifeartaigh, J. M. Pawlowski, V. V. Sreedhar
The quantisation of the two-dimensional Liouville field theory is investigated using the path integral, on the sphere, in the large radius limit. The general form of the -point…
Monopoles, Polyakov-Loops and Gauge Fixing on the Torus
C. Ford, U. G. Mitreuter, J. Pawlowski +2
We consider pure Yang Mills theory on the four torus. A set of non-Abelian transition functions is presented which encompass all instanton sectors. It is argued that these transiti…
Polyakov-Loops and Fermionic Zero Modes in QCD2 on the Torus
U. G. Mitreuter, J. M. Pawlowski, A. Wipf
A simple derivation of the free energy and expectation values of Polyakov-loops in via path integral methods is given. In the chosen gauge (which can be generalized to 4 di…
