PION - Translation in English - bab.la
http://www.freedictionary.org/?Query=pion 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 … See more 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 … See more 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 … See more • Pionium • Quark model • Static forces and virtual-particle exchange • Sanford-Wang parameterisation See more Theoretical work by Hideki Yukawa in 1935 had predicted the existence of mesons as the carrier particles of the strong nuclear force. … See more 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 See more Pions, which are mesons with zero spin, are composed of first-generation quarks. In the quark model, an up quark and an anti-down quark make up a π , whereas a down quark and an anti-up quark make up the π , and these are the antiparticles of one another. The neutral pion π … See more • Gerald Edward Brown and A. D.

I was going through the book High Energy Physics by DH Perkins. In the decay π 0 → 2 γ ( p h o t o n), the possible spin components of the system of photons S z can be 0 or 2. A statement in the book says, if the spin of of the pion is 1, then S z has to be zero. simple n easy hairstyles
