In slide 9,it shows accelerator coordinate is (x,y,z,px,py,pz;h,s) where s is azimuthal coordinate.I can't understand azimuthal coordinate s in geometry.Can you explain?ThanksVanadium 50 said:They explain why on slide 10.
The lab frame is a reference frame that is stationary and used to describe the motion of particles in a laboratory setting. The accelerator frame, on the other hand, is a reference frame that is moving at high speeds and is used to describe the motion of particles in an accelerator.
The lab frame and accelerator frame are related by the principle of relativity, which states that the laws of physics are the same in all inertial reference frames. This means that the observations made in the lab frame will be consistent with those made in the accelerator frame, as long as the relative velocities between the two frames are constant.
It is important to consider both frames because particles in an accelerator are moving at high speeds and may exhibit different behaviors than when they are at rest in the lab frame. By understanding the motion of particles in both frames, scientists can accurately interpret experimental results and make meaningful conclusions.
Time dilation, a consequence of special relativity, causes time to appear to pass slower for objects moving at high speeds. This means that measurements made in the accelerator frame may appear to take longer in the lab frame. Scientists must account for this when analyzing data from experiments in order to accurately determine the behavior of particles.
Yes, there are other frames of reference that are important in particle physics, such as the center-of-mass frame and the rest frame. The center-of-mass frame is the frame in which the total momentum of a system is zero, and is often used in particle collisions. The rest frame is the frame in which a particle is at rest, and is used to describe the properties of a particle without any external influences.
