Finsler度量和CPT
Finsler metrics and CPT
摘要：
讨论了类芬斯勒度规在洛伦兹对称破缺和CPT破坏中的作用。讨论了这种度规在量子引力和模拟系统中的各种物理实例。将强调这些案件之间的差异和相似之处。特别是在弦论中出现的D粒子的介质将被检查。在这种情况下，打破洛伦兹不变性，在量子涨落的水平，连同伴随CPT在某些情况下将进行分析。特别是它将显示中性介子对的相关性将被修改和重子生成的新贡献将出现。
英文摘要：
The role of Finsler-like metrics in situations where Lorentz symmetry breaking and also CPT violation are discussed. Various physical instances of such metrics both in quantum gravity and analogue systems are discussed. Both differences and similarities between the cases will be emphasised. In particular the medium of D-particles that arise in string theory will be examined. In this case the breaking of Lorentz invariance, at the level of quantum fluctuations, together with concomitant CPT in certain situations will be analysed. In particular it will be shown correlations for neutral meson pairs will be modified and a new contribution to baryogenesis will appear.
