Gravity dependence on rotation or spin direction is experimentally constrained for non-relativistic matter. Here, a method based on high-energy Compton scattering is developed to measure the gravitational interaction of accelerated charged particles. Within that formalism, the Compton spectra measured at HERA rule out the speculated anti-gravity possibility for antimatter at a confidence level close to 100 KW - gravitation: interaction (INSPIRE) KW - gravitation: coupling (INSPIRE) KW - energy: high (INSPIRE) KW - energy: low (INSPIRE) KW - electron: helicity (INSPIRE) KW - CP: violation (INSPIRE) KW - asymmetry: CP (INSPIRE) KW - positron (INSPIRE) KW - Compton scattering (INSPIRE) KW - general relativity (INSPIRE) KW - charged particle (INSPIRE) KW - antigravitation (INSPIRE) KW - DESY HERA Stor (INSPIRE) KW - antiparticle (INSPIRE) KW - rotation (INSPIRE) KW - parity (INSPIRE) KW - spin: dependence (INSPIRE) KW - interpretation of experiments (INSPIRE) KW - experimental results (INSPIRE) LB - PUB:(DE-HGF)16 UR - <Go to ISI:>//WOS:000526052300007 DO - DOI:10.1142/S0217732320500790 UR - https://bib-pubdb1.desy.de/record/437583 ER -
