Unraveling the Hubble tension with warm inflation
arXiv:2508.10835 · doi:10.1088/1361-6382/adf40a
Abstract
The validity of warm inflation is investigated in the light of recent CMB missions in both strong and weak dissipative regimes. The tensor to scalar ratio of various inflationary models is found to be consistent with the recent CMB results for different models of warm inflation. The role of dissipation on the popular models of warm inflation in the context of supersymmetry and string theory is investigated. Further, the effect of dissipation coefficient of warm inflation on the Hubble parameter and its role in accounting the Hubble tension is examined. Warm inflation embodies superstring theory and can provide a platform to test quantum gravity in multi field scenario.
