Occupation number formalism for arbitrary Nc baryons
(Elsevier Science, 2006-12)
A general method is presented for computing matrix elements of quark operators on baryonic states with low strangeness and arbitrary number of colors Nc. These results are useful in applications of the large Nc expansion ...
Baryon and meson density of states
(1993-12-01)
In a finite size bag like picture consisting of quarks (2 flavour) and gluons with SU(3) colour singlet restriction on the partition function and the chemical potential μ ≠ 0 with the constraint that the baryon number b = ...
Excited baryons and heavy pentaquarks in large- Nc QCD
(Springer, 2007-03)
We briefly discuss the large-Nc picture for excited baryons, present a new method for the calculation of matrix elements and illustrate it by computing the strong decays of heavy exotic states. © Società Italiana di Fisica ...
Unified model of baryonic matter and dark components
(Elsevier Science, 2008-08)
We investigate an interacting two-fluid cosmological model and introduce a scalar field representation by means of a linear combination of the individual energy densities. Applying the integrability condition to the scalar ...
Hadronic resonances with exotic electric charge
(Amer Physical Soc, 2017-10-20)
We classify the meson and baryon long lived resonances that may exist if quarks with electric charge 5/3 and -4/3 (in units of vertical bar e vertical bar) predicted by some 3-3-1 models do exist. Some of these exotic ...
Hadronic resonances with exotic electric charge
(2017-10-20)
We classify the meson and baryon long lived resonances that may exist if quarks with electric charge 5/3 and -4/3 (in units of |e|) predicted by some 3-3-1 models do exist. Some of these exotic resonances have the usual ...
Observed supersymmetry of hadrons and the tachyonless string models
(1992-12-01)
The experimental mesonic density of states ρmeson(m)≃ρbaryon(m) from 0.9 to 1.3 GeV. In this region the ρmeson fits the ρ(m) deduced for it from discrete bag model states. Beyond 1.3 GeV one can expect exotic mesons. If ...
