What are mesons and bosons?
Meson is a type of a Hadron and is a composite particle made up of quarks (and/or anti-quarks) which has integer spin and is hence classified as a Boson in accordance with the spin-statistics theorem. A meson is a composite particle and a vector boson is a spin 1 force carrier particle.

Are mesons bosons or fermions?
Mesons are intermediate mass particles which are made up of a quark-antiquark pair. Three quark combinations are called baryons. Mesons are bosons, while the baryons are fermions.
Which particles are mesons?
meson, any member of a family of subatomic particles composed of a quark and an antiquark. Mesons are sensitive to the strong force, the fundamental interaction that binds the components of the nucleus by governing the behaviour of their constituent quarks.
What are the differences between bosons and fermions?
Hint: Fermions are defined as the elementary particles which contain half integral spins whereas Bosons are defined as the particles having integral spins. Quarks and leptons, as well as most composite particles, like protons and neutrons, are fermions.
What are bosons particles?
In particle physics, a boson (/ˈboʊzɒn/ /ˈboʊsɒn/) is a subatomic particle whose spin quantum number has an integer value (0,1,2 …). Some bosons are elementary particles and occupy a special role in particle physics unlike that of fermions, which are sometimes described as the constituents of “ordinary matter”.
What are the characteristics of pseudoscalar mesons?
The pseudoscalar mesons consisting of up, down, and strange quarks only form a nonet. In high-energy physics, a pseudoscalar meson is a meson with total spin 0 and odd parity (usually notated as J P = 0− ).
What is a pseudoscalar particle?
Pseudoscalar particles, i.e. particles with spin 0 and odd parity, that is, a particle with no intrinsic spin with wave function that changes sign under parity inversion. Examples are pseudoscalar mesons. A pseudoscalar in a geometric algebra is a highest- grade element of the algebra.
What is the difference between a pseudoscalar and a reflection?
As reflections through a plane are the combination of a rotation with the parity transformation, pseudoscalars also change signs under reflections. One of the most powerful ideas in physics is that physical laws do not change when one changes the coordinate system used to describe these laws.
What is the difference between pseudoscalar and pseudovector?
A pseudoscalar, when multiplied by an ordinary vector, becomes a pseudovector (axial vector); a similar construction creates the pseudotensor . Mathematically, a pseudoscalar is an element of the top exterior power of a vector space, or the top power of a Clifford algebra; see pseudoscalar (Clifford algebra).
