Are there any experimental tests of the gravitational interaction of antimatter?

Mar 15, 2013 ... Eighty years ago today, the journal Physical Review published a paper by physicist Carl Anderson announcing the discovery of the positron. Positron Physics at Jefferson Lab e+@JLab. 2023 JLUO Annual Meeting. June 26th- 28th, 2023. (i). Positron White Paper. (ii) Two photon exchange. The Atomic, Molecular, Optical and Positron Physics (AMOPP) group explores many different topics and has both experimental and theoretical research programs in ...

A positron is the antimatter partner of an electron. It has exactly the same mass as an electron but has the opposite electric charge. A positron is the antiparticle of an electron. It has all the properties of an electron except for the polarity of the electrical charge, which is positive. Aug 23, 2024 ... Plasmas commonly found in and around extreme astrophysical objects have finally been produced in the laboratory.
