Advanced Intro to Quantum Mechanics

Advanced Intro to Quantum Mechanics

• Special Topic

2
Purpose

• Still very simplified, but covers more in-depth
  quantum mechanics
• Read the Intro to Particle Accelerators and Black
  Holes presentation first

3
What is Antimatter?

• Antimatter is the opposite of matter
• For each particle there is an antiparticle
• There is essentially an antiuniverse
• Should you meet your antiself the universe and
  antiuniverse would collapse

4
Quarks

• 6 types
• Up, down, top, bottom, charm, and strange
• Combinations make up other particles

5
Hadrons

• Particles made of quarks and/or gluons
• Come in 2 flavors baryons and mesons
• Baryons are a type of fermion
• Fermions obey the Pauli Exclusion Principle
• Made of 3 quarks
• Mesons are a type of boson
• Bosons do not obey the Pauli Exclusion
• Made of 2 quarks

What is the LHC Looking for?

• The Large Hadron Collider (LHC) at CERN is
  colliding protons together try to find a single
  predicted particle
• They want to find the Higgs Boson

9
Why do we care about the Higgs Boson?

• The Higgs Boson is predicted to be the particle
  that creates mass
• We know what mass is, but not what causes it
• If all matter is at its most basic energy, then
  what makes mass?

10
Higgs Boson

• Think of the Higgs Boson like someone others are
  drawn to
• Wherever they move others clump or group around
  them
• Where people group you have mass and density

11
Why this bothers us

• There are 4 basic parts to the model of reality
• Electromagnetism (How particles and waves
  interact)
• Strong Forces (Hold the nucleus together)
• Weak Forces (Control radioactivity and fusion)
• Mass (We have no understanding of this)

12
LHC

• The LHC brings us one step closer to having a
  full understanding of our world
• It will either prove there is a Higgs Boson, show
  we need a more powerful collider, or find
  something entirely new
