1932 Antielectron (or positron), the first antiparticle, discovered by Carl D. Anderson [13] (proposed by Paul Dirac in 1927 and by Ettore Majorana in 1928) : 1937 Muon (or mu lepton) discovered by Seth Neddermeyer, Carl D. Anderson, J.C. Street, and E.C. Stevenson, using cloud chamber measurements of cosmic rays [14] (it was mistaken for the pion until 1947 [15])
Thomson in 1897 was the first to suggest that one of the fundamental units of the atom was more than 1,000 times smaller than an atom, suggesting the subatomic particle now known as the electron. Thomson discovered this through his explorations on the properties of cathode rays.
Discovered in cosmic rays. The first strange particle. lambda baryons Λ: composite (baryons) never: University of Melbourne (Λ 0, 1950) [31] The first hyperon discovered. neutrino ν: elementary (lepton) Wolfgang Pauli (1930), named by Enrico Fermi: Clyde Cowan, Frederick Reines (ν e, 1956) Solved the problem of energy spectrum of beta decay ...
1897 J. J. Thomson discovered the electron; 1897 Emil Wiechert, Walter Kaufmann and J.J. Thomson discover the electron; 1898 Marie and Pierre Curie discovered the existence of the radioactive elements radium and polonium in their research of pitchblende; 1898 William Ramsay and Morris Travers discover neon, and negatively charged beta particles
1937 – Muon discovered by Carl David Anderson and Seth Neddermeyer; 1938 – Pyotr Kapitsa: Superfluidity discovered; 1938 – Otto Hahn, Lise Meitner and Fritz Strassmann Nuclear fission discovered; 1938–39 – Stellar fusion explains energy production in stars [citation needed] 1939 – Uranium fission discovered; 1941 – Feynman path ...
The first step, and most important by far, is “establishing a stable antimatter production line with much larger storage capacities”—something we don’t have the resources to do today.
Muon g-2 is a particle physics experiment at Fermilab to measure the anomalous magnetic dipole moment of a muon to a precision of 0.14 ppm, [32] [33] which is a sensitive test of the Standard Model. [34]
Scientists potentially uncovered a glueball particle, an enigmatic entity believed to be made entirely of the strong nuclear force's gluons. Scientists May Have Found a Particle Made of Pure Force ...
