关于中微子速度的Cohen约束和Escherhow约束的一般性

On the generality of the Cohen and Glashow constraints on the neutrino velocity

F. L. Villante, F. Vissani

摘要:

在中微子超光速的假设下,讨论了过程ν_μ \rightarrow ν_μ+ e^+ + e^-的运动学极限。我们的结果是在假设:i)存在一个能量和动量守恒的参考系; ii)Hamilton-Jacobi方程v=dE/dp成立; iii)目前关于不同能量下中微子速度的实验信息是正确的情况下得出的。我们表明,所考虑的过程是无法避免的,除非假设非常奇特的中微子色散定律。

英文摘要:

We discuss the kinematic limits for the process ν_μ\rightarrow ν_μ+ e^+ + e^- in the assumption that neutrinos are superluminal. We derive our results by assuming that: i) it exists one reference frame in which energy and momentum are conserved; ii) the Hamilton-Jacobi equation v=dE/dp is valid; iii) the present experimental information on the neutrino velocity at different energies are correct. We show that the considered process cannot be avoided unless very peculiar neutrino dispersion laws are assumed.
