タイトル：Status of the anomaly in b-> c tau nu

アブストラクト：
Recently, several new experimental results of the test of lepton flavor
universality (LFU) in B→D(∗) semi-leptonic decays have been announced from
the LHCb Run 1 and Run 2 data and the Belle II. Including these new data, a
global analysis still prefers the violation of the LFU between the tau and
light leptons which would imply the new physics (NP). We update a
circumstance of the b→cτν which describes B→D(∗) semi-leptonic decays.
Incorporating recent developments for the B→D(∗) form factors in the
Standard Model (SM), we observe a 4.4σ deviation from the SM prediction.
After overviewing the status of the SM prediction, we will discuss how to
probe the potential NP solutions at low energy and high energy experiments
(Belle II, LHC, EDM experiments and future lepton collider).
