The discovery of the antiproton p (a particle with the same rest
energy as a proton, 938 MeV, but with the opposite electric charge)
took place in 1956 through the following reaction: p + p → p+p+p+¯
p, in which accelerated protons were incident on a target of
protons at rest in the laboratory. The minimum incident kinetic
energy needed to produce the reaction is called the threshold
kinetic energy, for which the final particles move together as if
they were a single unit. Find the threshold kinetic energy to
produce antiprotons in this reaction.
please give a thumbs up.

can you helpme of third one problem Show that the threshold kinetic energy in the Laboratory for the production of n pions in the collision of protons with a hydrogen target is given by T= 2nm (1 + nm,/4mp) where m, and mp are respectively the pion and proton masses. A gamma ray interacts with a stationary proton and produces a neutral pion according to the scheme y + p → P +7° Calculate the threshold energy given Mp =...
3. (10 pts) High energy particle accelerators convert part of the energy of colliding particles into the masses of particles produced in the collisions. Consider a collision of two protons that produces two charged kaons. The mass of the proton is mp- 938.3 MeV/c2, and the mass of each kaon is mK 493.7 MeV/c2. The reaction is a) The total energy (kinetic energy and rest energy) and total momentum is conserved. Suppose one of the protons is at rest in...
There was a "bevatron" designed to accelerate a proton to such a high speed that when it collided with a proton at rest, two proton-antiproton pairs were created. That is, some of the accelerated proton's kinetic energy was enough to be converted into the mass of the new particles: p + p rightarrow (p + p) + (p + p). If the four particles on the right move along together as a single particle of rest mass M = 4m_p,...
In addition to its rest energy, a moving proton (p') has kinetic energy. This proton collides with a stationary proton (p), and the reaction forms a stationary neutron (n), a stationary proton (p), and a stationary pion (π+), according to the following reaction: p' + p → n + p + π+. The rest energy of each proton is 938.3 MeV, and the rest energy of the neutron is 939.6 MeV. The rest energy of the pion is 139.6 MeV....
