WebMore recent experiments with high-energy collisions show how a struck quark creates quark-anti-quark pairs that recombine in different ways to create a chain of mesons and baryons. The struck quark combines with a created antiquark to form a meson, leaving the quark partner of the antiquark to seek a new created antiquark, etc.

WebLH: −1, RH: −2. The tau ( τ ), also called the tau lepton, tau particle, tauon or tau electron, is an elementary particle similar to the electron, with negative electric charge and a spin of 1 2. Like the electron, the muon, and the three neutrinos, the tau is a lepton, and like all elementary particles with half-integer spin, the tau has ... WebElectron–positron annihilation occurs when an electron ( e −) and a positron ( e +, the electron's antiparticle) collide.At low energies, the result of the collision is the annihilation of the electron and positron, and the creation …
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 mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions π and π decaying after a mean lifetime of 26.033 nanoseconds (2.6033×10 seconds), … Web$\begingroup$ Lubos gave a complete answer, but one could add that nuclear forces are in analogy with the electromagnetic forces between molecules, the Van der Waals forces. There the mediator is the photon, but the moments of the charge distributions are what control the forces exerted between molecules.

WebBaryons and mesons are included in the overall class known as hadrons, the particles which interact by the strong force. Baryons are fermions , while the mesons are bosons . Besides charge and spin (1/2 for the baryons), two other quantum numbers are assigned to these particles: baryon number (B=1) and strangeness (S), which in the chart can be …

In S U ( 2), taking up quark and down quark as a doublet we can easily apply the isospin ladder operators to write the combination of 2 quark or 3 quark (baryon) systems. In S U ( 3) quark model, to get light pseudoscalar mesons, we need to combine a triplet and antitriplet to form an octet and singlet. bk precision 5492WebBaryons and Mesons in terms of their Quarks – A Level Physics.
