探测HERA的正电子引力

Probing Positron Gravitation at HERA

Vahagn Gharibyan

摘要:

粒子和反粒子引力相互作用的相等性在广义相对论中成立,并得到间接观测的支持。本文提出了一种基于高能康普顿散射的方法来测量加速带电粒子的引力相互作用。在这种形式主义中,HERA测量的康普顿光谱排除了正电子的反引力,并暗示正电子与引力场的耦合比电子弱1.3(0.2)%。

英文摘要:

An equality of particle and antiparticle gravitational interactions holds in general relativity and is supported by indirect observations. Here I develop a method based on high energy Compton scattering to measure the gravitational interaction of accelerated charged particles. Within that formalism the Compton spectra measured at HERA rule out the positron's anti-gravity and hint for a positron's 1.3(0.2)\% weaker coupling to the gravitational field relative to an electron.
