2. What is a quark?
- Elementary particle that carries an electric charge - Combine to create composite particles called Hadrons - Most common Hadrons include Neutrons and Protons - Only observed when combined due to color confinement
(Stefan's Slide)
Color Confinement:
     1. quarks are bonded by gluon tube
     2. gluon tube stretched to attempt isolation
     3. gluon tube doesn't break, anti-quarks created
     4. anti-quarks fly away and free themselves

3. Color Charge (Anti)red, (anti)green, (anti)blue
Anti-particles: Same mass, opposite charge
The color assignment is completely arbitrary, no relation
to colors we see
Strong force between quarks: Exchange particle=Gluon
Quarks can't be isolated completely and therefore they
are not able to be directly observed

4. First Generation Quarks
UP QUARK: Charge: +2⁄3 e Mass: 2.3 MeV/c2 The up quark is the least massive of all quarks. The up quark is thought to be extremely common and also exhibits all four fundamental forces which are gravity, electromagnetism, weak interactions and strong interactions. DOWN QUARK: Charge: −1⁄3 e Mass: 4.8 MeV/c2 The down quark is the second least massive of all quarks. The down quark likewise is thought to be very common and exhibits all four fundamental forces. Neutrons= (one up quark + two down quarks) Protons= (two up quarks + one down quark)

5. Second Generation Quarks
STRANGE QUARK: Charge: -1⁄3 e Mass: 95 MeV/c^2
Third lightest quark. Along with the strange antiquark, determines the strangeness of a particle, which describes the decay of particles in strong and electromagnetic reactions.
CHARM QUARK: Charge: +2⁄3 e Mass: GeV/c^2
Third most massive quark, found in charmed particles and charm. With charm antiquark, determines charm of a particle.

6. Third Generation Quarks
Top (t): Most massive of all quarks with a mass of ±.27 GeV/c^2. Charge is +2/3. Lifespan is ~5x10^-25 seconds. Only quark that doesn't hardonize.
Bottom (b): Second most massive quark with a mass of 4.2 GeV/c^2. Charge is -1/3. Decays into up or charm quark by the weak interaction. Lifetime is ~10^-12 seconds.
