Unlike the pion, the rho meson has spin " j " = 1 ( a vector meson ) and a much higher value of the mass.
12.
The rho mesons have a very short lifetime and their decay width is about with the peculiar feature that the decay widths are not described by a Breit Wigner form.
13.
Experimentally, it is observed that the masses of the octet of states, e . g ., the octet of vector mesons ( such as the rho meson ).
14.
In principle the charged rho mesons mix with the weak vector bosons and can lead to decay to an electron or muon plus a neutrino; however, this has never been observed.
15.
Here the strong force acts indirectly, transmitted as gluons, which form part of the virtual pi and rho mesons, which classically transmit the nuclear force ( see this topic for more ).
16.
Chernodub found, on the basis of the theory of quantum chromodynamics ( QCD ), that charged rho mesons They share the same quantum state and form a condensate, flowing together as one particle.
17.
Chernodub sees a possible explanation of his results in the quarks and antiquarks constituting the rho mesons being forced to move only along the magnetic field lines, which would render the rho mesons far more stable.

In the De Rujula & ndash; Georgi & ndash; Glashow description of hadrons, the rho mesons can be interpreted as a bound state of a quark and an anti-quark and is an excited version of the pion.
20.
Dirac had also solved the problem of putting the Tomonaga Schwinger equation into the Schr�dinger representation and given explicit expressions for the scalar meson field ( spin zero pion or pseudoscalar meson ), the vector meson field ( spin one rho meson ), and the electromagnetic field ( spin one massless boson, photon ).
