Estimate of the Branching Fraction of tau --> pi eta' nu_tau (2009)
Nussinov, Shmuel, Soffer, Abner
We calculate the expected branching fraction of the second-class-current decay tau --> pi eta' nu, motivated by a a recent experimental upper-limit determination of this quantity. The largest...
Soffer, Abner, Toki, Walter, Winklmeier, Frank
We describe a method for measuring CP-violation parameters from which the Cabibbo-Kobayashi-Maskawa angle $\gamma$ may be extracted. The method makes use of the total decay rates in $B^\pm \to...
Nussinov, Shmuel, Soffer, Abner
We consider the ``second-class current'' decay $\tau^-\to\pi^-\eta\nu_\tau$ from several points of view. We first focus on the decay rate as expected within standard weak interaction and QCD due to...
Isospin analysis of D0 decay to three pions (2008)
Gaspero, Mario, Meadows, Brian, Mishra, Kalanand, Soffer, Abner
The final state of the decay D0 --> pi+ pi- pi0 is analyzed in terms of isospin eigenstates. It is shown that the final state is dominated by the isospin-0 component. This suggests that isospin...
Improved measurement of (2 beta+gamma) (2005)
Sinha, Nita, Sinha, Rahul, Soffer, Abner
We propose to measure the Cabibbo-Kobayashi-Maskawa parameter (2 beta+gamma) using B^0 decays involving several intermediate states, and describe a general formalism that applies to a broad class of...
The Effect of $D-\bar D$ Mixing on the Measurement of $\gamma$ in $B\to D K$ Decays (2005)
Grossman, Yuval, Soffer, Abner, Zupan, Jure
$D-\bar D$ mixing is the source of the largest theoretical uncertainty in the extraction of $\gamma$ from $B\to D K$ decays. In the Standard Model, the mixing can have a rate close to its current...
Determination of the angle gamma using multibody D decays in B^+- -> D K^+- (2003)
Giri, Anjan, Grossman, Yuval, Soffer, Abner, Zupan, Jure
We describe a method for determining gamma using B^+- -> D K^+- decays followed by a multibody D decay. In the talk we focus on K_S pi^- pi^+ final state, but other modes such as D -> K_S K^- K^+ and...
Determining $\gamma$ using $B^\pm \to D K^\pm$ with multibody D decays (2003)
Giri, Anjan, Grossman, Yuval, Soffer, Abner, Zupan, Jure
We propose a method for determining $\gamma$ using $B^\pm\to D K^\pm$ decays followed by a multibody $D$ decay, such as $D \to K_S \pi^-\pi^+$, $D \to K_S K^-K^+$ and $D \to K_S \pi^-\pi^+\pi^0$. The...
Measuring $\gamma$ in $B^\pm \to K^\pm (K K^*)_D$ decays (2002)
Grossman, Yuval, Ligeti, Zoltan, Soffer, Abner
We develop a method to measure the CKM angle $\gamma$ without hadronic uncertainties from the analysis of $B^\pm \to K^\pm D^0$ and $K^\pm \D0bar$ followed by singly Cabibbo-suppressed $D$ decays to...
What can we learn from a measurement of sin(2 beta + gamma)? (2002)
Silva, Joao P., Soffer, Abner, Wolfenstein, Lincoln, Wu, Feng
The constraints on the value of the CKM phase gamma that may be achieved by prospective measurements of sin(2 beta) and sin(2 beta + gamma) are discussed. Significant constraints require quite small...
Measuring the Weak Phase gamma in Color Allowed B->DKpi Decays (2002)
Aleksan, Roy, Petersen, Troels, Soffer, Abner
We present a method to measure the weak phase gamma in the three-body decay of charged B mesons to the final states D K pi0. These decays are mediated by interfering amplitudes which are...
Impact of D0-D0bar mixing on the experimental determination of gamma (1999)
Several methods have been devised to measure the weak phase gamma using decays of the type B+- --> D K+-, where it is assumed that there is no mixing in the D0-D0bar system. However, when using these...
Discrete Ambiguities in the Measurement of the Weak Phase Gamma (1999)
Several time-independent methods have been devised for measuring the phase gamma of the Cabibbo-Kobayashi-Maskawa unitarity triangle. It is shown that such measurements generally suffer from discrete...
