Planck scale effects on the stochastic gravitational wave background generated from cosmological hadronization transition: A qualitative study

Abstract: We reconsider the stochastic gravitational wave background spectrum produced during the first order hadronization process, in presence of ultraviolet cutoffs suggested by the generalized uncertainty principle as a promising signature towards the Planck scale physics. Unlike common perception that the dynamics of QCD phase transition and its phenomenological consequences are highly influenced by the critical temperature, we find that the underlying Planck scale modifications can affect the stochastic gravitatio… Show more

“…In this respect to have a proper EoS becomes therefore crucial, especially when the stochastic background of GWs generated by any PT is known. It severely depends on the critical temperature 4 T * (in particular here T * (QCD) ∼ a few hundred MeV), [24,27,28].…”

“…In Refs. [24,28], frequencies related to other GW sources are discussed. 3 Recall that, in high energy regime, QCD is an asymptotic freedom and perturbative theory while, at low energy, it is strongly-coupled so that a perturbative approach is not useful [26].…”

“…So GUP modified equation of state will be reasonable to use in the study of the SGWB power spectrum. In this context, the GUP modified equations of state have been used to study the SGWP power spectrum in [33,34], and the possibility of detection of the SGWB signal has been discussed. In this paper, we intend to investigate the power spectrum of SGWB with linear quadratic GUP to study qualitatively whether the detection is more probable in the current epoch.…”
