strong force (Strong interaction)
exchange particle = Gluon
effects = protons and neutrons in the nucleus
weak force ( weak interaction)
exchange particle = W+ , W-
effects = Lepton (decay)
β- , β+
Electrostatic force
exchange particle = virtual photon
effects = anything with a charge
Gravity
exchange particle = Graviton (Higgs boson)
effects = anything with mass
muon
a lepton that is negatively charged and has a greater rest mass than an electron
pion (Pi meson)
a reason that consists of an up or down quark and an up and down antiquark
kaon (k meson)
a reason that consists of a strange quark or antiquark and another quark / antiquark
antimunon
antiparticle of the muon
hadron
partciles and antiparticle that can interact through the strong interaction
Baryons
Mesons
lepton
electrons, positrons, muons/antimuons, neutrinos and their antiparticles are classified as leptons because they cannot interact through the strong interaction. they interact through the weak interaction and, in the case of electrons, positrons, muons/antimuons through the electromagnetic interaction
baryon
a hardon consisting of three quarks
meason
a hardon consisting of a quark and an antiquark
antiquark
antiparticle of a quark
quark
protons and neutrons and other hardens consist of quarks. there are six types of quarks up, down, strange, charmed, top and bottom.
Baryon is a quantum number
Theoretical expression for the valve of some quantised property of a subatomic particle
What is the only stable baryon and every thing eventually decays into it
Proton
Kaon can decay into
Pions
Strange particles are particles that are produced through the strong interaction and decay through the …….
Weak interaction
Is strangeness is conservation in strong interactions
Yes
Cosmic ray showers
Source of high energy particles including pions and kaons
Observation of stray tracks in cloud chamber
Alpha thick and straight
Beta whipsy and thin
Observing high energy particles
Use of a geiger counter to detect a cosmic ray shower
