The startup of the LHC opens many new frontiers in precision flavour physics, in particular expanding the field of precision time-dependent CP violation measurements to the $B^0_s$ system. This contribution reviews the status of…
LHCb is the dedicated B physics experiment at the LHC and is due to start data taking later this year. Its goal is to search for new physics in very rare processes and make precision measurements of CP violation in B decays. The CKM angle…
An overview of plans for the measurement of gamma at the LHCb experiment will be shown. The gamma angle is the least accurately known parameter of the CKM unitary triangle. The LHCb experiment at the CERN LHC aims to perform precision heavy…
A combination of measurements sensitive to the CKM angle $\gamma$ from LHCb is performed. The inputs are from analyses of time-integrated $B^{+}\rightarrow DK^+$, $B^{0} \rightarrow D K^{*0}$, $B^{0} \rightarrow D K^+ \pi^-$ and $B^{+}…
In this proceeding I present the latest result by the LHCb collaboration in determining the CKM angle $\gamma$ ($(73^{+9}_{-10})^{\circ}$). The result is determined by combining several $B \to Dh$ analyses, and the latest results from the…
The LHCb approach for a precise determination of the CKM angle $\gamma$ from tree--level decays is presented. Up to 16 independent determinations, using a variety of beauty and charm mesons decay modes, are available at LHCb. Not all of…
LHCb is already providing leading measurements of time-dependent CP asymmetries with 1 fb$^{-1}$ of data. With the LHCb detector, and further one with the LHCb upgrade, very high-precision time-dependent CP measurements are expected to…
The LHCb experiment is in operation since 2009 and has provided measurements of the KM matrix with unprecedented precision. 50 years after the original paper we are in the position of pinning down the parameters of the theory, or possibly…
The time-dependent CP-violating observables accessible through Bs->DsK decays have been measured for the first time using data corresponding to an integrated luminosity of 1 inverse fb collected in 2011 by the LHCb detector. Using these…
The Belle experiment has measured the CKM angle $\gamma$ in a variety of ways. In this paper, we focused on the recent progress of time-dependent $\gamma$ analysis and the related measurements in Belle.
Precision measurements in charm physics offer a window into a unique sector of potential New Physics interactions. LHCb is poised to become a world leading experiment for charm physics, recording enormous samples with a detector tailored…
Measurement of the CKM phase gamma in B->DK decays can be potentially performed with high precision due to low theoretical uncertainties. However, the precision measurement requires very large experimental samples of B decays. This report…
Of the three angles that make up the CKM matrix, the least well known is gamma. A precision measurement of this quantity is highly desirable as it forms one of the arbitrary parameters in the Standard Model. Moreover, this is the one angle…
We present a short review of the measurements of the CKM angle gamma performed by the babar experiment. We focus on methods using charged B decays, which give a direct access to gamma and provide the best constraints so far.
We report results from the first measurements of the CKM angle $\gamma$ using $B\rightarrow DK$ decays with the LHCb experiment. Three well established methods are used to extract the CP observables. The updated measurement of $\gamma$ in…
I report on an updated combination of all currently available tree-level measurements of the CKM angle $\gamma$ from LHCb. This combination currently gives LHCb's most precise value of $\gamma = (73^{+9}_{-10})^\circ$ obtained from $B\to…
A sensitivity study for the measurement of the CKM angle $\gamma$ from $B^0_s\rightarrow \tilde{D}^{(*)0}\phi$ decays is performed using $D$ meson reconstructed in the quasi flavour-specific modes $K\pi$, $K3\pi$, $K\pi\pi^0$, and…
We review the most precise tests of the CKM model of flavour physics performed by the LHCb collaboration during the current year. These include world best measurements of both time-dependent and time-independent $C\!P$ violation in charm…
LHCb is a dedicated detector for b and c physics at the LHC. I will present a concise review of the detector design and expected performance together with some first results on the commissioning of the different sub-systems based on cosmic…
The LHCb collaboration has studied various promising ways to determine the Unitarity Triangle angle $\gamma$. Three complementary methods will be considered. The potential of the $B \to DK^{(*)}$ decays has been studied by employing the…
