WebPions. Pions (π–mesons) can be positive (π + ), negative (π –) or neutral (π 0) The anti–particle of the positive pion is the negative pion (and vice versa) The neutral pion is its own anti–particle. Pions are the lightest mesons, making them more stable than other types of meson. They were originally discovered in cosmic rays and ...

WebQuarks bind together in groups of twos and threes called hadron s via the strong force. Hadrons that consist of two quarks are called mesons, and those that consist of three quarks are called baryons. Examples of mesons include the pion and kaon, and examples of baryons include the familiar proton and neutron.

WebMar 22, 2005 · In a hadron collider, possible ways to access low-x is by increasing the collision energy or by looking at particles produced at forward rapidities, which preferentially selects collisions of large-x quarks with small-x gluons. In this talk, we examine forward particle production at RHIC, focusing on high energy neutral pion production at the ... WebE = 2m t. Because almost all of the energy of the collision is the result of top and antitop decay, we simply add the energies of the four jets, the soft muon, the muon and the neutrino before dividing by the two tops (actually a top and an antitop quark) to obtain the mass of the most recently discovered quark.
