How much kinetic energy take the particles after the collision?

Click For Summary
SUMMARY

The minimum kinetic energy required for a proton to initiate the reaction ##p+p\rightarrow p+n+\pi ^+## is calculated to be 292 MeV. The discussion highlights the importance of considering conservation of momentum and the differences between the center of mass (COM) frame and the laboratory (lab) frame when analyzing particle collisions. The second part of the problem focuses on how much of the initial kinetic energy is converted into the kinetic energy of the resulting particles post-collision.

PREREQUISITES
  • Understanding of particle physics and reactions, specifically proton collisions.
  • Knowledge of kinetic energy calculations in high-energy physics.
  • Familiarity with conservation of momentum principles.
  • Concept of reference frames, particularly center of mass and laboratory frames.
NEXT STEPS
  • Study the principles of conservation of momentum in particle collisions.
  • Learn about the differences between the center of mass frame and the lab frame in particle physics.
  • Explore kinetic energy calculations for particle reactions in high-energy physics.
  • Investigate the implications of energy conversion in particle collisions and resultant particle motion.
USEFUL FOR

Students and professionals in physics, particularly those focusing on particle physics, collision dynamics, and energy transformations in high-energy reactions.

Homework Statement


What is the minimum amount of kinetic energy of proton that hits another still proton so reaction ##p+p\rightarrow p+n+\pi ^+## is possible? How big part of the initial kinetic energy is used for kinetic energy of new particles?

Homework Equations


The Attempt at a Solution



##T_{min}=292MeV##

am... I don't really understand the second question? I calculated the minimum kinetic energy with presumption that ##p+n+\pi ^+## will have no kinetic energy after the collision of protons... So... what exactly answers the second part of this problem? O.o

You haven't mentioned conservation of momentum.
 
Also, consider the difference between how the collision looks in the COM frame vs. the lab frame. I assume the last question is being asked about the lab frame.
