The Standard Model Flashcards
Quarks and leptons are which particles?
The matter particles
Bosons are which particles?
Force mediating particles
The quark model includes the properties of
Charm, topness and bottomness
The properties of all hadrons can be described in
Terms of the quark model
The two types of hadrons are known as
Baryons and mesons
Baryons are made of
Three quarks
Neutrons and protons are examples of
Baryons
Protons and neutrons are not
As
Fundamental particles themselves
As they consist of constituents called quarks
All hadrons are thought to be
Consequently
Unstable to some degree
Subject to decay
The strong interaction can be used to explain the
Forces between hadrons
During nuclear reaction, the electrical charge of a hadron is
Conserved
During an interaction baryon number is
Conserved
Protons and neutrons are baryons with
Baryon number 1
Neutrons and protons within a nucleus are
Relatively stable
Free neutrons are
And decay to produce
Unstable, with a half life of approximately fifteen minutes
A proton and a beta particle
The half life of free protons is thought to be
Of the order of 10^32 years
All mesons are made up of
Two quarks
Examples of mesons are
Pions and Kaons
Electrons and neutrinos are members of
The fundamental particle group known as leptons
Bosons are both
Fundamental particles and force mediating particles
The four fundamental forces are
Strong
Weak
Gravitational
Electromagnetic
Bosons enable
Fundamental forces to act
During B+ decay
Positrons and neutrinos are produced
During B- decay
Electrons and antineutrinos are produced
Beta decay is caused by
A weak interaction involving quarks
The three fundamental particles are
Bosons, Leptons and Quarks
