Cosmological constraints on $Λ (α)$ CDM models with time-varying fine structure constant

Jin-Jun Zhang, Lu Yin, Chao-Qiang Geng

We study the $Λ (α)$ CDM models with $Λ (α)$ being a function of the time-varying fine structure constant $α$ . We give a close look at the constraints on two specific $Λ (α)$ CDM models…

Flavor Violating Higgs Couplings in Minimal Flavor Violation

Jin-Jun Zhang, Min He, Xiao-Gang He +1

Motivated by the rencent LHC data on the lepton-flavor violating (LFV) decays $h \to ℓ_{1} ℓ_{2}$ and $B_{s, d} \to ℓ_{1} ℓ_{2}$ , we study the Higgs-mediated flavor-changing neutr…
