I will review the status of factorisation predictions for charmless hadronic B meson decays. In particular, I will report on recent progress in obtaining a full NNLO calculation, and I will elucidate how non-perturbative methods as well as experimental measurements can help to further constrain the theoretical predictions.

We report preliminary measurements of the Branching Ratio (BR) for the charmless rare decays B0 -> pi0 pi0, B0 -> eta’ K*(892)0 and B+ -> Kbar*0 K*+. We also report the preliminary results for A_CP for B0 -> eta’ K*0 and the longitudinal fraction for B+ -> Kbar^*0 K*+. Previous Belle measurements of the BR for B^0 -> pi^0 pi^0 are significantly larger than theoretical expectations and employed...

We present the results of a new search for B-meson decays to omega omega, and omega phi. These modes, yet unseen, are related to B -> phi K* decays via an SU(3) rotation. Their study can therefore provide information regarding the unexpectedly small value of the longitudinal spin component (f_L) measured in B -> phi K* decays. We also report the first Dalitz-plot analysis of charged B mesons...

Charmless B hadrons decays offer rich opportunities to test the Standard Model. For example, CP violation in charmless charged two-body and three-body B decays provides ways to measure the CKM angle gamma and to search for New Physics. Also, vector-vector final states provide additional interesting observables. Here, we present the latest LHCb results on hadronic charmless B decays putting...

I review the extraction of gamma / phi3 from tree-level B -> DK decays. In particular, I discuss the effects of direct CP violation in D decays and the ultimate theory uncertainty.

The datasets that the LHCb and Belle II experiments are expected to collect in the coming years will allow a 1-degree precision measurement of the angle gamma (phi3) using Bch->D(*)0K(*) decays. To reach this goal a number of subleading effects must be taken into account. We disuss these corrections, including the impact of D-Dbar mixing and possible CPV in D decays.
Determination of the parameters of the Cabibbo-Kobayashi-Maskawa (CKM) matrix are important as checks on the consistency of the Standard Model, and as ways to search for new physics. Among the angles of the CKM unitarity triangle, gamma is the least-well constrained by direct measurements. In this talk, we report the determination of the angle gamma through the combination of measurements...

Quantum correlation results from D threshold data will be reviewed, with an emphasis and more details on the recent results. Some key issues to address in the future are also highlighted.

A review of the Belle gamma/phi3 measurements from B->DK will be presented. Results using the ADS, GLW and GGSZ methods are presented, along with the combined measurement of gamma/phi3 from Belle.

We report on an updated combination of all currently available tree-level measurements of the CKM angle gamma at LHCb. For the first time we include results obtained from a time integrated analysis of B+ -> DK+, D -> KS0Kpi decays; and of B0 -> DK∗0, D -> K+K-, pi+pi-, K+pi-, pi+K- decays; and from a time-dependent analysis of Bs0 -> DsK decays. The results represent the world's best...

In Run-I of the LHC, LHCb has collected a dataset corresponding to an integrated luminosity of 3 inverse fb. Much larger datasets are expected in Run-II and in the Upgrade era. An outlook of the capabilities of LHCb is given with a number of direct CPV processes involving electro-weak and gluonic penguins and a measurement of gamma using tree diagrams as examples.
Pablo Goldenzweig (University of Rochester (US))
The next generation B-factory under construction at SuperKEKB / Belle II is targeted to collect an integrated luminosity of 50ab^-1, starting in 2016. This large dataset will open up a new era of precision measurements in flavor physics. This talk will focus on the potential for a sub-degree precision measurement of the least constrained angle of the CKM unitarity triangle, gamma, and the...
