Collaborative Efforts in Particle Physics The field of particle physics is constantly changing and as time goes on, our knowledge and understanding of the nature of particles changes too Par...
Strange Particles Strange particles are particles that include a strange or anti-strange quark An example of these are kaons Strange particles always: Are produced through the strong interac...
Properties of Quarks & Antiquarks Quarks The three most common flavours of quarks are: up, down and strange The majority of hadrons are made up of different combinations of these quarks ...
Leptons & Antileptons Leptons are a group of fundamental (elementary) particles This means they are not made up of any other particles (no quarks) Leptons interact with other part...
Pions & The Strong Nuclear Force Pions Pions (π–mesons) can be positive (π+), negative (π–) or neutral (π0) The anti–particle of the positive pion is the negative pion (and vice versa) T...
Baryon Number The baryon number, B, is the number of baryons in an interaction B depends on whether the particle is a baryon, anti-baryon or neither Baryons have a baryon number B = +1 Anti-...
Antimatter The universe is made up of matter particles (protons, neutrons, electrons etc.) All matter particles have antimatter counterparts Antimatter particles are identical to their matte...
α & β Decay Equations Alpha Decay Alpha decay is common in large, unstable nuclei with too many protons The decay involves a nucleus emitting an alpha particle and decaying into a differ...
Strong Nuclear Force In the nucleus, there are electrostatic forces between the protons due to their electric charge and gravitational forces due to their mass Comparatively, gravity is a ve...
