Neutral Rho

Some articles on rho:

Rho Meson
... In particle physics, a rho meson is a short-lived hadronic particle that is an isospin triplet whose three states are denoted as ρ+, ρ0 and ρ− ... After the pions and kaons, the rho mesons are the lightest strongly interacting particle with a mass of roughly 770 MeV for all three states ... The rho mesons have a very short lifetime and their decay width is about 145 MeV with the peculiar feature that the decay widths are not described by a Breit-Wigner form ...

Famous quotes containing the word neutral:

    I feel the carousel starting slowly
    And going faster and faster: desk, papers, books,
    Photographs of friends, the window and the trees
    Merging in one neutral band that surrounds
    Me on all sides, everywhere I look.
    John Ashbery (b. 1927)
