Is Energy of Gauge Bosons matched by Binding Energy?

Everytime a photon leaves an atom, the energy of that photon is matched by the increase in binding energy of that atom - right? If so would the change of energy in the form of radiation be equivalent to the change of binding energy?

Is the aggregate binding energy of particles in the universe increasing with time?

It is possible in an eternal cyclic universe for radiation to come back and decrease the binding energy particles, replenshing light elements such as hydrogen?

Is it possible in the Big Bang theory?

Overall energy is conserved, yes.
(I'm assuming we use the rest frame of the atom and neglect recoil.)

The most common nuclear reaction is the fusion of hydrogen to helium. Therefore: Yes.

No.

No.

While you can split helium with photons of sufficient energy the process is so rare that it is completely negligible.
 

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}...
