We discuss the isospin symmetry breaking quantity ∆ ±0 ≡ Γ(B ± → ρ ± γ)/2Γ(B 0 → ρ 0 γ)−1, and the direct CP violation in B ± → ρ ± γ within and beyond the standard model. After showing that the leading-order calculation would be a good approximation in such models, we argue that measurements of these quantities would be able to disentagle physics beyond the standard model.

Littlest Higgs model with T-parity predicts the existence of the neutral, weakly interacting, new gauge boson BH , which can be seen as an attractive dark matter candidate. We study production of the new gauge boson BH via eγ and ep collisions. We find that BH can be abundantly produced via the subprocesses e γ → LBH and γq → BHQ, which might give rise to characteristic signals. Some discussion...
