Elementary Particles Fundamental forces in Nature
... • They are always produced in pairs. • They are created in a strong interaction, decay to strongly interacting particles, but have lifetimes characteristic of the weak interaction. To explain this, a new quantum number, called strangeness, S, was introduced. ...

Assumptions of the ideal gas law:
... Because the system involves no external forces, friction, or forces of attraction or repulsion between particles; no force is exerted on a particle until it collides with the wall or another gas molecule. When a particle hits a wall perpendicular to the x-axis, an elastic collision results in an exa ...

Lesson 30: Particle Physics
... Why is a magnetic field often applied across a bubble chamber? What can the curvature of a particle's track in a magnetic field reveal about the particle?! What is the wavelength of the photons produced in electron-positron pair annihilation? (2.4 x 10-12 m)! Describe and explain the differences in ...

The Spectator-Induced Electromagnetic Effect on Meson Production
... Abstract. The electromagnetic interaction between the spectator system and the charged mesons produced in the course of the high energy heavy ion collision was studied experimentally and theoretically in earlier works [1, 2]. This effect was found to result in very large distortions of the final sta ...
