Field theory description of vacuum replicas

A. V. Nefediev, J. E. F. T. Ribeiro

In this paper we develop a systematic quantum field theory based approach to the vacuum replica recently found to exist in effective low energy models in hadronic physics. A local…

Singularity Resolution in Gauged Supergravity and Conifold Unification

J. D. Edelstein, A. Paredes, A. V. Ramallo

We obtain a unified picture for the conifold singularity resolution. We propose that gauged supergravity, through a novel prescription for the twisting, provides an appropriate fra…

Let's Twist Again: General Metrics of G(2) Holonomy from Gauged Supergravity

J. D. Edelstein, A. Paredes, A. V. Ramallo

We construct all complete metrics of cohomogeneity one G(2) holonomy with S^3 x S^3 principal orbits from gauged supergravity. Our approach rests on a generalization of the twistin…

Relativistic Quark Model Calculation of the l1, l2 Coefficients of the Chiral Lagrangian

Felipe J. Llanes-Estrada, Pedro Bicudo

We briefly report on a relativistic quark model scheme to calculate the O(P^4) pion-pion vertex in the planar approximation and in the chiral limit. The calculation is reduced to t…

Quantum field theory approach to the vacuum replica in QCD

A. V. Nefediev, J. E. F. T. Ribeiro

Quantum field theory is used to describe the contribution of possible new QCD vacuum replica to hadronic processes. This sigma-like new state has been recently shown to be likely t…

Hierarchy plus anarchy in quark masses and mixings

J. A. Aguilar-Saavedra

We introduce a new parameterisation of the effect of unknown corrections from new physics on quark and lepton mass matrices. This parameterisation is used in order to study how the…
