加速运动物质中的味中微子振荡
Flavor neutrino oscillations in matter moving with acceleration
摘要:
本文简要地回顾了中微子味振荡在匀速运动物质中的研究。然后考虑了加速运动物质中的中微子味振荡。我们开发了一种方法,是有效的非相对论和相对论物质运动。对于这两种情况下的有效中微子加速物质的潜力和中微子味振荡概率和Mikheyev-Smirnov-Wolfenstein共振条件进行了评估。在零物质加速度极限下得到的结果再现了静止物质情况下的相应表达式。所开发的方法适用于中微子味振荡的情况下,旋转的物质。所获得的结果可能对天体物理学应用有意义。
英文摘要:
A short review on studies of neutrino flavor oscillations in moving with a constant speed matter is presented. Then neutrino flavor oscillations in matter moving with acceleration are considered. We develop an approach that is valid for both non-relativistic and relativistic matter motion. For both these cases the effective neutrino potentials in accelerating matter are obtained and neutrino flavor oscillation probabilities and the Mikheyev-Smirnov-Wolfenstein resonance conditions are evaluated. The obtained results in the limit of zero matter acceleration reproduce the corresponding expressions for the case of matter at rest. The developed approach is applied for neutrino flavor oscillations in the case of rotating matter. The results obtained might be of interest for astrophysical applications.
