Measurement of the decays B -> eta lv(l) and B -> eta ' lv(l) in fully reconstructed events at Belle

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tara Nanut, Jun Yong Kim

We report branching fraction measurements of the decays B+ -> eta l(+)v(l) and B+ -> eta'l(+)v(l) based on 711 fb(-1) of data collected near the (sic)(4S) resonance with the Belle experiment at the KEKB asymmetric-energy e(+)e(-) collider. This data sample ...

Freeze-out of baryon number in low-scale leptogenesis

Mikhail Chapochnikov, Inar Timiryasov, Shintaro Eijima

Low-scale leptogenesis provides an economic and testable description of the origin of the baryon asymmetry of the Universe. In this scenario, the baryon asymmetry of the Universe is reprocessed from the lepton asymmetry by electroweak sphaleron processes. ...

Theta dependence in holographic QCD

Andrea Manenti

We study the effects of the CP-breaking topological theta-term in the large N-c QCD model by Witten, Sakai and Sugimoto with N-f degenerate light flavors. We first compute the ground state energy density, the topological susceptibility and the masses of th ...
