Geometric Rényi mutual information induced by localized particle excitations in quantum field theory
Willy A. Izquierdo, David R. Junior, Gastão Krein
Quantum field theory exhibits rich spatial correlation structures even in the vacuum, where entanglement entropy between regions scales with the area of their shared boundary. Whil…
Study of the Emergence of a Gluon Mass Scale from Center Vortices Using a Wave-Functional Formalism
David R. Junior, Gastão Krein, Luis E. Oxman +1
Lattice simulations and theoretical analyses consistently identify center vortices and monopoles as key nonperturbative configurations in Yang-Mills theory. In the continuum, the e…
Bound states of massive complex ghosts in superrenormalizable quantum gravity theories\
Manuel Asorey, Gastao Krein, Miguel Pardina +1
One of the remarkable differences between renormalizable quantum gravity with four-derivative action and its superrenormalizable polynomial generalizations is that the latter admit…
Reflection positivity in a higher-derivative model with physical bound states of ghosts
Manuel Asorey, Gastão Krein, Miguel Pardina +1
The inclusion of higher derivatives is a necessary condition for a renormalizable or superrenormalizable local theory of quantum gravity. On the other hand, higher derivatives lead…
The Quark Structure of the Nucleon and Moat Regimes in Nuclear Matter
Theo F. Motta, Gastão Krein
We employ a model of nuclear structure that takes into account the quark substructure of the baryons to understand the behavior of static two-point correlation functions of meson f…
Parton distribution and fragmentation functions with massive gluons
Gustavo B. Bopsin, Bruno El-Bennich, Gastão Krein +2
The correct description of the hadron's structure requires understanding how quarks and gluons form the observable hadrons and how they are distributed within them. Two key nonpert…
