Mesons are part of the Hadron group along with Baryons, and are subatomic particles composed of one quark and one antiquark. (Baryons being composed of three quarks.) Quarks and leptons are elementary particles, and that is the fundamental difference.
leptons are basic (elementary particles) and are influenced by the weak force
hadrons are composites of smaller particles known as quarks and are influenced by the strong force
Leptons
LEPTONS are basically family of fundamental subatomic particles consisting of electron, muon, tauon(tau) particles with their corresponding neutrinos They have spin 1/2. They do not strongly interact.
Baryons are particles composed of three, "color-neutralizing" quarks. Protons and neutrons are the most well-known examples. Mesons are particles composed of a quark/antiquark pair. The pion is the best-known example.
They are leptons, bosons, hadrons, fermions etc.
Pion is another name for "pi meson". They're mesons composed of an up or down quark and an up or down antiquark. "Mixed" mesons (one up, one down) are charged;the form where both the quark and antiquark are up or down are neutral.
all particles in particle physics are divided into two sub groups the hadrons and leptons the difference between them being that baryons interact by strong force leptons interact by weak force the hadron group can be further subdivided into two more groups the mesons and baryons muons are part of the lepton group
The answer is no: electrons are fermions while mesons are bosons.
Hadrons are particles composed of quarks. There are two (known) types of hadrons: mesons, which consist of a quark and an antiquark, and baryons, which consist of three quarks (or three antiquarks). Leptons are a separate type of particles. They are not composed of quarks, but are elementary particles in their own right.
Quarks experience all four fundamental interactions, whereas leptons only experience three. Leptons do not experience the strong interaction.
There are two types of subatomic particles hypothesized to comprise protons and neutrons. Elementary particles having mass by the types of quarks, leptons and bosons are the first. The second are composite particles, which include baryons, mesons, and leptons.
Mesons are particles consisting of one quark and one antiquark.
η-mesons, π-mesons and κ-mesons, k-mesons.
Leptons are just called that: "leptons". (One example of a lepton is an electron.)
Forces acting between nucleons are called nucler forces.
We now know there are are six quarks (or called flavours of quarks), which are grouped into 3 pairs (or generations); up & down, charmed & strange and top and bottom. It is these fundamental particles which form neutrons, protons etc, which are collectively known as hadrons, (it is mainly the up and down which form the world around us). The quarks are peculiar as they posses a charge which is a fraction of that for the electron. There are two types of hadron, the Baryon which is a system of three quarks (e.g. the proton) or Mesons, a two quark system containing a quark - antiquark pair (e.g. the pion or pi-meson). Leptons are particles such as muons and electrons, there are 6 leptons in total, each with their anti-lepton counterpart. For the electron, muon and taon (which are referred to as different flavours of the lepton) there is a corresponding neutrino (a lepton) associated with it. Difference between the two: Leptons do not participate in the strong interaction and are generally not seen within the nucleus. Bosons are often force carrier particles (these are typically referred to as gauge bosons). In the prevailing Standard Model of physics, the photon is one of four gauge bosons in the electroweak interaction; the other three are denoted W+, W− and Z0 and are responsible for the weak interaction.
Quarks and leptons are not elements.
