conservation laws and further interactions Flashcards
(19 cards)
what is a particle interaction
any interaction between subatomic particles
what is muon decay
a muon interacts with a boson to form an electron, electron antineutrino and a muon neutrino
what is anti-muon decay
an anti-muon interacts with a boson to form a positron, electron neutrino and a muon antineutrino
Whenever a particle decays into other particles, we call the process…
particle decay
what three decays are responsible for the weak force
beta plus decay
beta minus decay
muon decay
how are strange quarks made
the strong nuclear force
what is special about strange particles
they are created in pairs
what do positive kaons decay into
anti muons
muon neutrino
what do negative kaons decay into
neutral pions
muons
muon antineutrino
what do neutral kaons decay into
positive muons
negative muons
when strange particles decay it is always a result of
the weak force
what do a negative pion and a proton collide to produce
neutral kaon
Lamba baryon
what do a positive pion and a proton collide to produce
positive kaon
positive sigma baryon
what are the types of conservation laws
charge
baryon number
lepton number
strangeness
is strangeness conserved in strange particle production
yes
is strangeness conserved in strange particle decay
no
for a strange interaction to be viable the strangeness can only
increase by 1
decrease by 1
remain the same
how to work out an unknown particle from a particle interaction
state the force responsible for the interaction
write out the values for the conservation laws
use the values to work out the conservation laws for the unknown particle
why are decay equations limited
as they dont show the exchange particles
