Would a proton decay into smaller particles if you accelerate it into higher speeds without colliding it into another proton?
 
Physics news on Phys.org
No.
How could it? The laws of physics are the same in every inertial frame. There is nothing special about our laboratory frame. In its rest frame it is simply a proton just as before.

There could be proton decay, of course, but I guess that's not what your question is about - if it exists it applies to all protons.
 
I see. Just to make sure I understand fully, the simple process of accelerating a proton has no decaying effects on it?
 
Wouldn't the higher speed increase the lifetime of the proton?
 
In our lab frame, and assuming protons decay at all: Sure. Not that it matters, their lifetime is so long that we won't see a decay in accelerators anyway.
 

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
