TransPlanckian Censorship on Dark Dimension Inflation
Luis A. Anchordoqui, Ignatios Antoniadis, Jules Cunat
It was proposed that extra dimensions can acquire large size by higher dimensional inflation connecting two large hierarchies in particle physics and cosmology, namely the weakness…
Cosmological history after higher dimensional inflation
Luis A. Anchordoqui, Ignatios Antoniadis, Jules Cunat
It was proposed that extra dimensions can acquire large size by higher dimensional inflation connecting two large hierarchies in particle physics and cosmology, namely the weakness…
New leading contributions to non-gaussianity in single field inflation
Ignatios Antoniadis, Auttakit Chatrabhuti, Jules Cunat +1
We compute the bispectrum of primordial density perturbations in CMB to second order in the slow-roll parameters of single field inflation. We correct previous results and found th…
Bispectrum from five-dimensional inflation
Ignatios Antoniadis, Auttakit Chatrabhuti, Jules Cunat +1
It was proposed that five-dimensional (5D) inflation can blow up the size of a compact dimension from the 5D Planck length to the micron size, as required by the dark dimension pro…
Bispectrum at NLO in single field inflation: conservation and squeezed limit
Ignatios Antoniadis, Auttakit Chatrabhuti, Jules Cunat +1
In a recent paper, we computed the bispectrum of primordial density perturbations in CMB to second order in the slow-roll parameters of single field inflation, and found logarithmi…
SUSY at the FPF
Luis A. Anchordoqui, Ignatios Antoniadis, Karim Benakli +2
Experimental searches for supersymmetry (SUSY) are entering a new era. The failure to observe signals of sparticle production at the Large Hadron Collider (LHC) has eroded the cent…
