Reexamining the perturbative renormalizability of the coupled triplets
Manuel Pavon Valderrama
I reexamine the perturbative renormalizability of chiral two-pion exchange in two-nucleon scattering for coupled triplets when one-pion exchange has been fully iterated at leading…
Regulator constraints for the perturbative renormalizability of attractive triplets
Manuel Pavon Valderrama
Nuclear effective field theory organizes the calculation of observables as a power series in terms of the ratio of soft and hard momentum scales. The rigorous implementation of thi…
Scattering amplitudes versus potentials in nuclear effective field theory: search for a potential compromise
Manuel Pavon Valderrama
In effective field theory physical quantities, in particular observables, are expressed as a power series in terms of a small expansion parameter. For non-perturbative systems, for…
A comparison of two possible nuclear effective field theory expansions around the one- and two-pion exchange potentials
Manuel Pavon Valderrama
In the effective field theory formalism nuclear forces are organized as a low energy expansion. Usually the lowest order in this expansion corresponds to the non-perturbative itera…
The pentaquark and its partners in the molecular picture
Mao-Jun Yan, Fang-Zheng Peng, Mario Sánchez Sánchez +1
The LHCb collaboration has detected a new hidden-charm pentaquark with the quantum numbers of a baryon: the . This pentaquark will be interpreted as a $\bar{…
