Chapter 44, Problem 41AP
An unstable particle, initially at rest, decays into a proton (rest energy 938.3 MeV) and a negative pion (rest energy 139.6 MeV). A uniform magnetic field of 0.250 T exists perpendicular to the velocities of the created particles. The radius of curvature of each track is found to be 1.33 m. What is the mass of the original unstable particle?

Chapter 37, Problem 045
In a high-energy collision between a cosmic-ray particle and a particle near the top of Earth's atmosphere, 110 km above sea level, a pion is created.The
pion has a total energy E of 1.68 x 105 MeV and is traveling vertically downward. In the pion's rest frame, the pion decays 35.0 ns after its creation. At
what altitude above sea level, as measured from Earth's reference frame, does the decay occur? The rest energy of a pion is 139.6 MeV.

An alpha particle with kinetic energy 7.70 MeV collides with an 14N nucleus at rest, and the two transform into an 17O nucleus and a proton. The proton is emitted at 90° to the direction of the incident alpha particle and has a kinetic energy of 4.44 MeV.The masses of the various particles are alpha particle, 4.00260 u; 14N, 14.00307 u; proton, 1.007825 u; and 17O, 16.99914 u. In MeV, what are (a) the kinetic energy of the oxygen nucleus and (b) the Q of the reaction? (Hint:The speeds of the particles are much less than c.)
The very massive Higgs particle (mass 125 GeV/c2) is created when two protons traveling at equally high speeds but in opposite directions collide head‑on. The mass of a proton is 938.27 MeV/c2. In order to make a Higgs particle when they collide, each proton must have a minimum kinetic energy of 62.5 GeV.
What is the minimum total energy E(min) of each proton?
E(min) = ? eV
