Scale Independent Unified Quark Physics

Abstract

Based on available particle data, up quark mass is 2.15 MeV/c², down quark mass is 4.7 MeV/c² and their mass ratio is 0.46(5). In an earlier paper, the authors proposed a simple method for estimating the six quark masses. In this paper, the authors propose very simple methods for estimating the nuclear stability and nuclear binding energy and successfully extend the quark model to low energy scale nuclear physics. Topics covered are: 1) Hint of final unification and Up and Down quark rest masses, 2) Strong coupling constant, 3) Nucleon rest masses, 4) Nuclear stability, 5) Nuclear binding energy, 6) Strong interaction range, 7) Nuclear charge radius, 8) RMS charge radius of proton, 9) RMS charge radii of atomic nuclei and 10) Magic numbers. At the stable mass number of Z, nuclear binding energy seems to be proportional to the sum of 2Z number of up quarks rest energy and Z number of down quarks rest energy. It is interesting to note that binding energy near to stable mass number seems to be independent of the mass number. Finally an attempt is made to fit the SEMF energy coefficients.
