Book excerpt: The discovery of the J/psi meson in 1974 paved the way for the presence of three families of quarks in the Standard Model of Particle Physics. The production mechanism of J/psi at the LHC is not well understood, and several models have been proposed to explain it, such as the Color Singlet and Color Octet models. The associated production of J/psi meson with a W boson offers an additional insight on the production of J/psi.
