Physical Review D, 1979. Rafael Abela We have continued the measurement of the muon momentum p μ + in the decay π + → μ + v μ of pions at rest. The new result p μ + = 29.79179±0.00053 MeV/ c , and the assumption of a vanishing neutrino mass m νμ lead to a charged pion mass of 139.56996±0.00067 MeV/ c 2 , 3.5 standard deviations higher than the current world average of the mass obtained from pionic X-rays. A neutral pion (rest energy 135 MeV) moving at 0.7c decays into a pair of photons.

The result is p μ + =(29.79139 ± 0.00083) MeV/ c . The consequences of this value for the rest masses of the muon neutrino and of the charged pion … 2010-02-02 Abstract We have measured the momentum of muons from the decay π+ → μ+νμ at rest to be pμ+ = 29.79207±0.00012 MeV/c. This result leads to a laboratory upper limit of 0.16 MeV (CL = 0.9) for the muon-neutrino mass. The cosmological upper limit of the neutrino mass, the muon mass and the new pμ+-value yield the pion mass mπ+ = 139.57031 ± 0.00016 MeV. Decay involving only massive particles Problem: A slowly moving antiproton is captured by a deuteron at rest producing a neutron and a neutral pion.

Pion decay at rest

• Pion is spin zero: so the spins of the ν and μ are opposite. • Weak interaction only couples to RH chiral anti-particle states. Thus to create a pion of rest energy 135 MeV, it is necessary to give the incoming proton These muons arise from pion decaying at rest still inside, but near the.

Pion decay at rest

Ask Question Asked 4 years, 4 months ago. Active 1 year, 5 months ago. Viewed 8k times 2. 1 $\begingroup$ a pion at rest can decay into a muon and a neutrino. Conservation of energy and 3-momentum require. Conservation pion, muon, neutrino A pion (mπ = 273 me) at rest decays into a muon (mμ = 207 me) and a neutrino (mν = 0).Find the kinetic energy and momentum of the muon and the neutrino in MeV. Solution by Michael A. Gottlieb: (I choose units such that c = 1, and assume that me = 0.511MeV.) Since the pion is at rest conservation of momentum dictates that the momenta of the Pion Decay‐at‐Rest Neutrino Sources for Precision Studies of the Standard 3x3 Neutrino Paradigm Snowmass Workshop on Froner Capability Brookhaven Naonal Lab April 17, … 1 Lecture 10 February 1, 2002 Example: pi meson decay A pion has a rest energy of 135MeV. It decays into two gamma rays (photons).
