论文摘要

对阳性状态的三胞胎状态的三光子歼灭中某些角相关性的研究,可以用作探针的探针,并在松弛部门中探测潜在的CP和CPT侵入效应。我们使用此过程介绍了CP和CPT测试的观点,该过程使用新的检测系统记录在正电子歼灭能量范围(Jagiellonian PET(J-PET))中的光子。我们证明了该系统具有前所未有的运动学构型范围的三光子歼灭的能力,并测量了旋转旋转和an灭平面方向之间的CPT-ODD相关性,精度至少通过尊重的顺序提高了精确度。我们还讨论了控制和减少检测器不对称的手段,以便J-PET设置最有能力的an灭光子光子和动量之间的相关性的首次测量,而迄今为止从未研究过。

Study of certain angular correlations in the three-photon annihilations of the triplet state of positronium, the electron-positron bound state, may be used as a probe of potential CP and CPT-violating effects in the leptonic sector. We present the perspectives of CP and CPT tests using this process recorded with a novel detection system for photons in the positron annihilation energy range, the Jagiellonian PET (J-PET). We demonstrate the capability of this system to register three-photon annihilations with an unprecedented range of kinematical configurations and to measure the CPT-odd correlation between positronium spin and annihilation plane orientation with a precision improved by at least an order of magnitude with respect to present results. We also discuss the the means to control and reduce detector asymmetries in order to allow J-PET to set the first measurement of the correlation between positronium spin and momentum of the most energetic annihilation photon which has never been studied to date.
