Bondpionen var för övrigt den första perennerna som odlades i Sverige enbart för dess skönhets skull. The pion can be thought of as one of the particles that mediate the residual strong interaction between a pair of nucleons. This interaction is attractive: it pulls the nucleons together. Written in a non-relativistic form, it is called the Yukawa potential. The pion, being spinless, has kinematics described by the … Visa mer In particle physics, a pion (or a pi meson, denoted with the Greek letter pi: π ) is any of three subatomic particles: π , π , and π . Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest … Visa mer In the standard understanding of the strong force interaction as defined by quantum chromodynamics, pions are loosely portrayed as Goldstone bosons of spontaneously broken chiral symmetry. That explains why the masses of the three kinds of pions are … Visa mer • Pionium • Quark model • Static forces and virtual-particle exchange • Sanford-Wang parameterisation Visa mer Theoretical work by Hideki Yukawa in 1935 had predicted the existence of mesons as the carrier particles of the strong nuclear force. … Visa mer The use of pions in medical radiation therapy, such as for cancer, was explored at a number of research institutions, including the Los Alamos National Laboratory's Meson Physics Facility, which treated 228 patients between 1974 and 1981 in Visa mer Pions, which are mesons with zero spin, are composed of first-generation quarks.
