A torsion-full geometry producing a CPT violating axial background which generates a dispersion relation explicitly dependent on helicity. Considering the decay of the heavy right handed neutrino into leptons and and anti-leptons and the corresponding charged Higgs, I have been working on the Boltzmann equations to calculate the out of equilibrium abundances of the leptons and anti-leptons to give a value of the asymmetry generated.

产生违反轴向背景的CPT的扭转满几何图形，其产生显式依赖于螺旋度的色散关系。考虑到重的右手中微子衰变成轻子和反轻子以及相应的带电希格斯，我一直在用玻尔兹曼方程来计算轻子和反轻子的不平衡丰度，以给出产生的不对称值。
