Well, guess I'll add me two cents in.  What will happen is that a packet of protons will collide with each other from different ends at sufficient energy levels that will  break both proton packets up into the particles of matter ( quarks, and leptons) and the particles of force (bosons).  They want to study the strong and weak nuclear forces, and electromagnetic energy as well as the elusive Higgs field.  

They want to know why a neutron decays into a proton and electron instead of a proton decaying into a neutron.

         want to study the different colors of quarks, their spins, symmetry
                                 how glueons work, what make up glueons
                                 and what the heck is the Higgs field or force that keeps matter the way it is.

 
Now, our star, the Sun has been plowing protons together for around 4.5 billion year and we are still here.  We have also done it for the last 50 years, combining protons together and releasing ity bettie packets of photons in all ranges of the electromagetic spectrum.
