  In this research, the production cross sections for QCD matter, neutrino and
dark energy due to acceleration of Universe is calculated. To obtain these
cross sections, the Universe production cross section is multiplied by the
particle or dark energy distribution in accelerating Universe. Also missing
cross section for each matter and dark energy due to formation of event
horizon, is calculated. It is clear that the cross section of particles
produced near event horizon of Universe is much larger for higher acceleration
of Universe. This is because as the acceleration of Universe becomes larger,
the Unruh temperature becomes larger and the thermal radiations of particles
are enhanced. There are different channels for producing Higgs boson in
accelerating Universe. Universe maybe decay to quark and gluons, and then these
particles interact with each other and Higgs boson is produced. Also, some
Higgs boson are emitted directly from event horizon of Universe. Comparing
Higgs boson cross sections via different channels, it is observed that at lower
acceleration, a_Universe<2.5 a_(early Universe), the Universe will not be able
to emit Higgs, but is still able to produce a quark and eventually for
a_Universe<1.5 a_(early Universe) the Universe can only emit massless gluons.
As the acceleration of Universe at the LHC increases, a_Universe>2.5 a_(early
Universe), most of Higgs boson production will be due to Unruh effect near
event horizon of Universe. Finally comparing the production cross section for
dark energy with particle cross sections, it is found that the cross section
for dark energy is dominated by QCD matter, Higgs boson and neutrino. This
result is consistent with previous predictions for dark energy cross section.
