3 days ago · The process is called annihilation and describes how a particle and an antiparticle can destroy and convert mass into energy. The description of annihilation is governed by Einstein's equation known as E = mc² where mass and energy are related.
Jun 11, 2024 · Feynman diagram, a graphical method of representing the interactions of elementary particles, invented in the 1940s and ’50s by the American theoretical physicist Richard P. Feynman. Introduced during the development of the theory of quantum electrodynamics as an aid for visualizing and calculating.
3 days ago · In the pair production process, the photons fall on a nucleus and electron and positron is formed γ → → e− +e+ e − + e +, while in annihilation the reverse process of pair production takes place e− +e+ e − + e + → → γ.
4 days ago · nsider electron-positron annihilation processes as initial states, produc-ing particle-antiparticle pairs without experiencing color interactions at tree level. The selected final states are therefore the W+W−, with the advantage of their mass but the drawback of their significantly short lifetime, and the μ+μ− and τ+τ−, with the advanta.
5 days ago · With increasing annealing temperature (above 600 °C), the thermal activation leads to dislocation unpinning and, consequently, results in a fast intrinsic annihilation process in dislocation cells.
Jun 24, 2024 · A triplet–triplet annihilation-based upconversion (TTA-UC) system, employing a multichromophore assembly, is convenient to harvest low-energy photons for light energy conversion and optoelectronic applications.
Jun 14, 2024 · Matter-antimatter annihilation seems like an inevitability, but does it really happen 100% of the time? And when they do annihilate, what’s the physics principle mandating that they do so?...
