We perform a comprehensive SU(3)-flavor analysis of charmed mesons decaying to two pseudoscalar SU(3)-octet mesons. Taking into account SU(3)-breaking effects induced by the splitting of the quark masses, m_s != m_{u,d}, we find that existing data can be described by SU(3)-breaking of the order 30%. The requisite penguin enhancement to accomodate all data on CP violation tends to be even larger than the one extracted from Delta a_{CP}^{dir}(K^+K^-,pi^+pi^-) alone, strengthening explanations…

Beauty baryon nonleptonic decays into decuplet baryons and CP -asymmetries based on an SU(3) -flavor analysis

We consider charmless weak decays of beauty baryons into decuplet baryons and pseudoscalar mesons in a general framework based on the SU(3)-flavor decomposition of the decay amplitudes. The dynamical

Testing SU(3) flavor symmetry in semileptonic and two-body nonleptonic decays of hyperons

The semileptonic decays and two-body nonleptonic decays of light baryon octet ($T_8$) and decuplet ($T_{10}$) consisting of light $u,d,s$ quarks are studied with the SU(3) flavor symmetry in this

Unification of flavor SU(3) analyses of heavy Hadron weak decays

Analyses of heavy mesons and baryons hadronic charmless decays using the flavor SU(3) symemtry can be formulated in two different forms. One is to construct the SU(3) irreducible representation

SU(3)_{F} in nonleptonic charm decays

We present updated results of an SU(3)-flavor analysis of D→ PP decay data including linear breaking and no further assumptions. The global fit is consistent with nominal (∼ 30%) SU(3)F breaking and

The emergence of the ΔU = 0 rule in charm physics

A bstractWe discuss the implications of the recent discovery of CP violation in two-body SCS D decays by LHCb. We show that the result can be explained within the SM without the need for any large

CP Asymmetries in Charm Decays into Neutral Kaons.

A new CP-violation effect in charm decays into neutral kaons is found, which results from the interference between two tree amplitudes with the mixing of final-state mesons, which is much larger than the direct CP asymmetries in these decays.

SU(3) in D decays: From 30% symmetry breaking to 1 0 − 4 precision

Flavor SU(3) symmetry, including 30% first-order SU(3) breaking, has been shown to describe adequately a vast amount of data for charmed meson decays to two pseudoscalar mesons and to a vector and a

SU(3) sum rules for charm decay

A bstractWe present flavor SU(3) sum rules for D → PP and D → PV decay amplitudes, that are valid to second order in symmetry breaking by the strange quark mass spurion. Decay rate sum rules are also

Direct CP violation in the hadronic charm decays provides a good testing ground for the Kobayashi-Maskawa mechanism in the Standard Model. Any significant deviations from the expectation would be

Repercussions of flavour symmetry breaking on CP violation in D-meson decays

A bstractWe investigate to what extent the recently measured value for a non-vanishing direct CP asymmetry in D0 → K+K− and D0 → π+π− decays can be accommodated in the Standard Model (SM) or

Shedding light on CP violation in the charm system via D→Vγ decays.

It is shown that in new physics models generating CP violating ΔC=1 chromomagnetic dipole operators, sizable direct CP asymmetries in radiative D→P(+)P(-)γ decays (P=π, K), with M(PP) close to the ρ or the φ peak, can be expected.
