Llanes Estrada, Felipe José ; Bicudo, Pedro ; Cardoso, Marco ; Van Cauteren, Tim | Polska Akademia Nauk, Instytut Fizyki | 2009-05-26We observe that excited hadrons provide an opportunity to probe from experiment the power-law running of the quark mass in the mid infrared, while the condition m(k)texto impreso
Llanes Estrada, Felipe José ; Bicudo, Pedro ; Cotanch, Stephen R | American Physical Soc | 2006-03-03We report an odderon Regge trajectory emerging from a field theoretical Coulomb gauge QCD model for the odd signature J(PC) (P=C=-1) glueball states. The trajectory intercept is clearly smaller than the Pomeron and even the omega trajectory's in[...]texto impreso
Bicudo, Pedro ; Cardoso, Marco ; Llanes Estrada, Felipe José ; Van Cauteren, Tim | Amer Physical Soc | 2016-09-07We study the conjectured “insensitivity to chiral symmetry breaking” in the highly excited light baryon spectrum. While the experimental spectrum is being measured at JLab and CBELSA/TAPS, this insensitivity remains to be computed theoretically [...]texto impreso
We argue that three-quark excited states naturally group into quartets, split into two parity doublets, and that the mass splittings between these parity partners decrease higher up in the baryon spectrum. This decreasing mass difference can be [...]
