“…In this section we extend the results of the derivation of Hawking radiation for scalar fields to Higgs boson in cyclic Universe [12,13,[22][23][24]. We show that the ground state for Higgs boson is a maximally entangled two-mode squeezed state on outside and inside Hilbert spaces of surface horizon.…”

“…These particles produce during the phase transition after the big bang explosion as the temperature goes down below some critical temperature. Then they decay to QCD matters [12,13].Since the temperature of early universe is very high, we expect more particles to be produced from Higgs bosons. In fact there can be an enormous amount of quark and gluon production from Higgs boson, much more than expected from normal pQCD processes [14,15].…”

First, by using cylindrically symmetric model, the quantum state for cyclic Universe is studied. It is shown that the ground state for oscillating cylindrical Universe is a maximally entangled with two-mode squeezed states on expanding and contracting Hilbert spaces of Universe. Next, the production cross section for each Universe state is obtained. It is observed that the probability for producing each state in cyclic Universe depends on different oscillating frequencies of Universe in space-time directions.After that, the effect of Universe oscillation on Higgs boson cross section is considered. To calculate the production cross section for Higgs boson, the production cross section for each Universe state is multiplied by thermal distribution of Higgs boson .It is found that in each Universe state, different amount of Higgs boson is produced. Finally, the signature of Higgs boson near surface horizon of oscillating Universe is studied. When Higgs bosons produce, they decay to quarks and gluons. Thus an enhancement of these partons can be a signature of Higgs boson inside the cyclic Universe.

“…Comparing this figure with Figs. (2)(3)(4)(5)(6)(7)(8), we find that the cross section for dark energy is dominated by QCD matter, Higgs boson and neutrino. This result is consistent with previous calculation for dark energy.…”

“…According the Unruh idea, there is a similar effect in flat space for a detector undergoing the acceleration of Universe to a detector near event horizon of black hole [4]. Following Hawking's discovery that asymptotically-flat stationary black holes emit thermal radiation, the detector in accelerating Universe appears to be in a heat bath at the Unruh temperature, (𝑇 𝑈 = ℏ𝑎 𝑈𝑛𝑖𝑣𝑒𝑟𝑠𝑒 2𝜋𝑘 𝐵 𝑐 where 𝑎 𝑈𝑛𝑖𝑣𝑒𝑟𝑠𝑒 is the acceleration of Universe) [5,6].…”

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, < 2.5 , the Universe will not be able to emit Higgs, but is still able to produce a quark and eventually for < 1.5 the Universe can only emit massless gluons. As the acceleration of Universe at the LHC increases, > 2.5 , 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.
