Two protons (each with mass mp = 1.67 x 10-27 kg) are initially moving with equal speeds in opposite directions. They continue to exist after a head-on collision that also produces a neutral pion of mass mp = 2.40 x 10-28 kg (Fig.). If all three particles are at rest after the collision, find the initial speed of the protons. Energy is conserved in the collision.

- 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. Number UnitsAn electron-positron collider runs with symmetric beam energies of E(e^+) = E(e^−) = 102 GeV.At each orbit ∆E = 2.2 GeV has to be replaced for each beam particle by the accelerating units.The accelerator has 24 units available; each unit can replace an energy of ∆E = 100 MeV perorbit. a). The researchers want to create the Standard-Model Higgs boson but don’t know its massyet. Argue why the production rate via the direct process e +e− → H is negligible and name the process which can be used instead. Draw a Feynman diagram of this process. State the mechanism responsible for the energy loss and state how the energy loss per orbit scales with the beam energy. b). Name two possible final states of this process and how they can be detected in a modernparticle detector, which consists of a tracker, an EM calorimeter, a hadronic calorimeterand a muon system in radial direction.
