Physicists found no CPT symmetry violations in orthopositronium decays

Physicists found no CPT symmetry violations in orthopositronium decays #physics #found #science

P. Moskal et al / Nature, 2021 Physicists have verified the fulfillment of CPT symmetry in the processes of three-photon decay of orthopositronium with an accuracy that turned out to be three times greater than in previous searches. They looked for a correlation between the spin of the orthopositronium and the plane in which photons propagate after its annihilation. The value they discovered…

The behavior of volcanoes has been linked to the state of magma in the reservoir #geology #magma #science

Razvan-Gabriel Popa et al. / Nature Geoscience, 2021 The character of a volcanic eruption is determined by the crystallinity, the content of dissolved volatiles and water in the melt in the magma reservoir. Volcanologists came to this conclusion after analyzing 245 eruptions of 75 volcanoes in subduction zones. Explosive eruptions are typical for magmas with a dissolved water content in the…
