Flavour Distributions in the Nucleons: SU(2) Sea Asymmetry or Isospin Symmetry Breaking?
Bo-Qiang Ma, Andereas Schaefer, Walter Greiner
The Gottfried sum rule violation reported by the New Muon Collaboration(NMC) was interpreted as indication for a flavour asymmetry of the sea quark in the nucleons. We investigate…
Finite volume of baryons and the mass limit for neutron stars
Qi-Ren Zhang, Bo-Qiang Ma, Walter Greiner
We confirmed the following idea by numerical calculation: The extended structure of baryons may make the nuclear equation of state stiffer at higher density while keeping the compr…
On the Linearized Artin Braid Representation
F. Constantinescu, F. Toppan
We linearize the Artin representation of the braid group given by (right) automorphisms of a free group providing a linear faithful representation of the braid group. This result i…
String fine tuning
G. Savvidy, K. Savvidy
We develop further a new geometrical model of a discretized string, proposed in [1] and establish its basic physical properties. The model can be considered as the natural extentio…
