The neutral ρ^0 meson decays by the strong interaction into two pions according to ρ^0 →π^ π^-, with a halflife of about 10^-23  s. The neutral K^0 meson also decays into two pions according to K^0 →π^ π^- but with a much longer half-life, about 10^-10  s . How do you explain these observations? | Numerade

SOLVED: A particle called phi-meson (Φ) has a rest mass of 1020 MeV/c. It decays into a pair of kaons (K and K'), each of which has a rest mass of 494 MeV/c^2. By carrying out calculations in the frame of reference in which the phi-meson is at rest, use the conservation of relativistic momentum and the conservation of total relativistic energy to calculate both the relativistic kinetic energy (in MeV) and the magnitude of the relativistic momentum (in MeV/c) of each of the kaons after the decay

Meson - Definition, Meaning & Synonyms

The ρmeson is a particle of spin J=1 and mass 770 MeV / c^2 occurring in three charge states ρ^ , ρ^0, ρ^-. It decays to a pair of spinless pions. Show that while ρ^± →π^0 π^±and ρ^0 →π^ π^-are allowed, ρ^0 →π^0 π^0 is forbidden. | Numerade

The Pi Meson An elementary particle called a pi meson (or pion for short) has an average lifetime of 2.6 ×10^-8 when at rest. If a pion moves with a speed of 0.89c relative to Earth, find (a) the average lifetime of the pion as measured by an observer on Earth and (b) the average distance traveled by the pion as measured by the same observer. (c) How far would the pion have traveled relative to Earth if relativistic time dilation did not occur? | Numerade
