半旋扭相互作用中的无质量费米子混合
Massless Fermion Mixing for Semispinorial Torsional Interaction
摘要:
我们考虑一种几何方法来处理场论,其中在物质场方程中存在扭转,并且我们发展了一对单手旋量的扭转-自旋耦合的结果;我们表明这些相互作用具有一种改变味道的中性流的结构,从而引起两个无质量费米子场的混合:由于半旋子的扭转相互作用导致了无质量费米子的混合,我们推测这种机制可能是中微子振荡的原因。
英文摘要:
We consider a geometric approach to field theory in which torsion is present in the matter field equations, and we develop the consequences of the torsion-spin coupling for a pair of single-handed spinors; we show these interactions to have the structure of a flavour-changing neutral current giving rise to a mixing for two massless fermion fields: as torsional interactions for semispinors entail mixing for massless fermions we speculate that this mechanism could be responsible for oscillations of neutrinos.
