The ∆-resonance in a finite volume#1
We study the extraction of ∆-resonance parameters from lattice data for small quark masses, corresponding to the case of an unstable ∆. To this end, we calculate the spectrum of the correlator of two ∆-fields in a finite Euclidian box up-to-and-includingO(ǫ) in the small scale expansion using infrared regularization. On the basis of our numerical study, we argue that the extraction of the param...
متن کاملRoper Resonance in a Quark-diquark Model
We discuss a new description for the Roper resonance, the first nucleon excited state of JP = 1/2+, in a model of strong diquark correlations. Treating the scalarisoscalar and axial-vector–isovector diquarks as independent degrees of freedom, two states having nucleon quantum numbers are constructed. Due to the scalar and axial-vector nature of the diquarks, the two nucleon states have differen...
متن کاملCompleting the Picture of the Roper Resonance.
We employ a continuum approach to the three valence-quark bound-state problem in relativistic quantum field theory to predict a range of properties of the proton's radial excitation and thereby unify them with those of numerous other hadrons. Our analysis indicates that the nucleon's first radial excitation is the Roper resonance. It consists of a core of three dressed quarks, which expresses i...
متن کاملBlood Flow Simulation in an Aorta with a mild coarctation Using Magnetic Resonance Angiography and Finite Volume Method
Coarctation of the aorta is one of the five main congenital cardiovascular failures, accounting for 6–8 percent of these failures. This research aimed to simulate the blood flow of a seventeen-year-old male teen with a mild coarctation at one-third of his aorta's descending branch. The simulation was performed by extracting the domain and the input pulsatile velocity signal as the boundary cond...
متن کاملElectroexcitation of the Roper resonance in the relativistic quark models
The amplitudes of the transition γ∗N → P11(1440) are calculated within light-front relativistic quark model assuming that the P11(1440) is the first radial excitation of the 3q nucleon state. The results are compared with those obtained in close approaches by other authors and with standard nonrelativistic calculations. One of the reasons for this study was to present all these results within u...
