A Possible Structure Model of the Vacuum: The Body Center Cubic Model of the Vacuum Material

摘要

This paper has deduced the baryon spectrum using only 2 flavored quarks u andd (each of them has three colored members). From Dirac's sea concept and thequark confinement idea, we conjecture and then assume that the quarks (in thevacuum state) compose colorless particles (uud and udd, hereafter will becalled the Lee Particles). Moreover, the Lee Particles lead in a natural way tothe construction - a body center cubic lattice in the vacuum. Consequently,there exists a strong interaction periodic field with body center cubicperiodic symmetries and an electromagnetic interaction periodic field (from thecharged Lee Particles uud) with simple cubic periodic symmetries in the vacuum.In terms of the energy band theory, using a point baryon approximation (i.e.,omitting the structure of the Lee Particles), and from the symmetries of thestrong interaction periodic field, we have deduced the intrinsic quantumnumbers (I, S, C, b, Q) of all baryons and a unified mass formula from whichall baryon masses can be found. This theoretical baryon spectrum is inaccordance with the experimental results in both intrinsic quantum numbers andmasses. These results show that various baryons are the energy band excitedstates of the Lee Particles. We also predict some new baryons: \Lambda^0(2559), \Lambda ^0(4279), \Xi_C(3169), \Omega ^-(3619), \Lambda_C^+(6659),\Lambda_b^0(10159) ... Furthermore, from the electromagnetic interactionperiodic field of the vacuum material, we predict a super heavy electronspectrum E(166 Gev), E(332 Gev), E(498 Gev) ... We suggest that experiments tofind the super heavy electron spectrum and long lifetime baryon \Lambda^0(2559) should be done.
