Breakdown of the operator product expansion in the 't Hooft model
Jorge Mondejar, Antonio Pineda
We consider deep inelastic scattering in the 't Hooft model. Being solvable, this model allows us to directly compute the moments associated with the cross section at next-to-leadi…
Forward virtual Compton scattering and the Lamb shift in chiral perturbation theory
David Nevado, Antonio Pineda
We compute the spin-independent structure functions of the forward virtual-photon Compton tensor of the proton at one loop using heavy baryon chiral perturbation theory and dispers…
Non-relativistic Quantum Mechanics versus Quantum Field Theories
Antonio Pineda
We briefly review the derivation of a non-relativistic quantum mechanics description of a weakly bound non-relativistic system from the underlying quantum field theory. We highligh…
Constraints on Regge models from perturbation theory
Jorge Mondejar, Antonio Pineda
We study the constraints that the operator product expansion imposes on large inspired QCD models for current-current correlators. We focus on the constraints obtained by goi…
Hybrid potentials versus gluelumps
Antonio Pineda
A potential model description of heavy quarkonium can be rigorously deduced from QCD under some circumstances. The potentials can be unambiguously related with Wilson loops with gl…
Phenomenological impact of the resummation of logs of alpha in heavy quarkonium
Antonio Pineda
Here we would like to review recent progress on the resummation on logarithms of in heavy quarkonium. We will mainly focus on the phenomenological relevance of these achievem…
