I read a lot about the so-called "missing" energy in hadronic collisions. I always thought that it was mainly due to neutrinos and also nuclear deformations, but today I read that "on average, 30% of the energy is missing in a hadronic collision", where is all this energy going?

  • $\begingroup$ Why can't 30% be due to neutrinos? Semileptonic decays of heavy quarks have high branching fractions. $\endgroup$ – dukwon Nov 4 '18 at 20:21
  • $\begingroup$ If the quotation from the unspecified source is talking about "the energy" $\sqrt s$ as opposed to the transverse energy, it could also be including (near-)collinear particles that 'escape' down the beam pipe. $\endgroup$ – David Schaich Nov 11 '18 at 11:32
