slide4. IB Physics Data Booklet<br>
slide5. Fundamental Particles<br>
slide6. Classifying Particles<br>
slide7. Baryons All Baryons are formed from a combination of 3 quarks or antiquarks u d Up Quark Charge = Down Quark Charge = Proton Neutron u u u d d d 2/3 -1/3 (uud) (udd) +1 0<br>
slide8. Mesons All Mesons are formed from a combination of a quark and antiquark Kaon D-Meson 0 -1<br>
slide9. Quark Confinement Quarks have never been observed on their own The amount of energy required to overcome the strong nuclear force holding the quarks together gets converted into mass and forms a new quark pair<br>
slide10. Conservation For an interaction to be possible, the following must stay conserved: This interaction is valid because all properties are conserved 1 1 0 0 0 0 1 -1 0 1 -1 0<br>
slide11. Conservation Yes
Valid No
Invalid<br>
slide12. Exchange Particles At the fundamental level of particle physics, forces are explained in terms of the transfer of exchange particles (gauge bosons) between the two particles experiencing the force These interactions are not observable, so we call them virtual particles Repulsion Attraction<br>
