The New Physics Reach of Null Tests with and Decays
Rigo Bause, Marcel Golz, Gudrun Hiller +1
processes are unique probes of flavor physics in the up-sector within and beyond the Standard Model (SM). SM tests with rare semileptonic charm meson decays are based…
Lepton Flavor Universality tests through angular observables of decay modes
Damir Becirevic, Marco Fedele, Ivan Nisandzic +1
We discuss the possibility of using the observables deduced from the angular distribution of the decays to test the effects of lepton flavor universalit…
Testing the standard model with decays
Nico Adolph, Gudrun Hiller, Andrey Tayduganov
The photon polarization in decays can be extracted from an up-down asymmetry in the system, along the lines of the method known to $B \to K_1 (…
Angular analysis of B -> J/psi K1 : towards a model independent determination of the photon polarization with B-> K1 gamma
E. Kou, A. Le Yaouanc, A. Tayduganov
We propose a model independent extraction of the hadronic information needed to determine the photon polarization of the b-> s gamma process by the method utilizing the B -> K1 gam…
Angular distributions of decays and search of New Physics
Damir Becirevic, Svjetlana Fajfer, Ivan Nisandzic +1
We derive the expressions for the full angular distributions of and decays and discuss the spectra on each angle s…
Probing New Physics with distributions in
Yasuhito Sakaki, Minoru Tanaka, Andrey Tayduganov +1
Recent experimental results for the ratios of the branching fractions of the decays and came as a surprise and lead to a d…
Testing leptoquark models in
Yasuhito Sakaki, Minoru Tanaka, Andrey Tayduganov +1
We study potential New Physics effects in the decays. As a particular example of New Physics models we consider the class of leptoquark models and put t…

Damir Becirevic, Andrey Tayduganov
We discuss the uncertainty related to the amount of unwanted events in the sample of . Those events can increase the…
Future prospects for the determination of the Wilson coefficient
Damir Becirevic, Emi Kou, Alain Le Yaouanc +1
We discuss the possibilities of assessing a non-zero from the direct and the indirect measurements of the photon polarization in the exclusive deca…

Damir Becirevic, Nejc Kosnik, Andrey Tayduganov
Recent experimental results for the ratio of the branching fractions of and decays came as a surprise and lead to a discus…
The strong decays of K1 resonances
Andrey Tayduganov, Emi Kou, Alain Le Yaouanc
We investigate the K1--> K pi pi strong interaction decays. Using the 3P0 quark-pair-creation model to derive the basic parametrization, we discuss in detail how to obtain the vari…
Determining the photon polarization of the b --> s gamma using the B --> K1(1270) gamma --> (K pi pi) gamma decay
Emi Kou, Alain Le Yaouanc, Andrey Tayduganov
Recently the radiative B decay to the strange axial-vector mesons, B --> K1(1270) gamma, has been observed with rather large branching ratio. This process is particularly interesti…
