Probability densities of the effective neutrino masses m_β and m_ββ

Meloni, Davide; Di Iura, Andrea

We compute the probability densities of the effective neutrino masses m_β and m_ββ using the Kernel Density Estimate (KDE) approach applied to a distribution of points in the (m_min ,m_ββ) and (m_β ,m_ββ) planes, obtained using the available Probability Distribution Functions (PDFs) of th…

Constraining the ionized gas evolution with CMB-spectroscopic survey cross-correlation

Ma, Yin-Zhe

We forecast the prospective constraints on the ionized gas model f_gas (z) at different evolutionary epochs via the tomographic cross-correlation between kinetic Sunyaev-Zeldovich (kSZ) effect and the reconstructed momentum field at different redshifts. The experiments we consider are the Planck and CMB Stage-4 survey for CMB and the SDS…

Higgs inflation from new Kähler potential

Choudhury, Sayantan; Pal, Supratik; Chakraborty, Trina

We introduce a new class of models of Higgs inflation using the superconformal approach to supergravity by modifying the Kähler geometry. Using the above-mentioned mechanism, we construct a phenomenological functional form of a new Kähler potential followed by construction of various types of models which are characterized by a superconformal symm…
