Dark dimension and the standard model landscape
LA Anchordoqui, I Antoniadis, J Cunat - Physical Review D, 2024 - APS
We study the landscape of lower-dimensional vacua of the standard model (SM) coupled to
gravity in the presence of the so-called “dark dimension” of size R⊥ in the micron range …

[HTML][HTML] Cosmological implications of ns≈ 1 in light of the Hubble tension
F Takahashi, W Yin - Physics Letters B, 2022 - Elsevier
Recently, a low-z measurement of the Hubble constant, H 0= 73.04±1.04 km/s/Mpc, was
reported by the SH0ES Team. The long-standing Hubble tension, ie the difference between …
