Stringy Threshold Corrections in D-brane Systems
Satoshi Iso, Noriaki Kitazawa, Takao Suyama
We investigate string amplitudes by using the partial modular transformation which we introduced in our previous works. This enables us to extract stringy threshold corrections fro…
Inflaton as a pseudo-Nambu-Goldstone boson
Noriaki Kitazawa
In the realistic model of cosmic inflation the inflaton potential should be flat and stable under quantum corrections. It is natural to imagine that there is some symmetry behind a…
Reionization process dependence of the ratio of CMB polarization power spectra at low-
Noriaki Kitazawa
We investigate how much the ratio of cosmic microwave background (CMB) polarization power spectra at low- () depends on the proces…
Gauge Symmetry Restoration by Higgs Condensation in Flux Compactifications on Coset Spaces
Satoshi Iso, Noriaki Kitazawa, Takao Suyama
Extra-dimensional components of gauge fields in higher-dimensional gauge theories will play a role of the Higgs field and become tachyonic after Kaluza-Klein compactifications on i…
Polarization of CMB and possible time dependence of dark energy
Noriaki Kitazawa
Dark energy has been introduced to explain the present accelerating expansion of the universe. In the LambdaCDM model, the present standard model of cosmology, dark energy is descr…
Polarizations of CMB and the Hubble tension
Noriaki Kitazawa
Future precision measurements of CMB polarizations can shed new light on the problem so called Hubble tension. The Hubble tension comes from the difference of the evolutions of the…
