Strong phases, asymmetries, and SU(3) symmetry breaking in D --> K pi decays
Dao-Neng Gao
Motivated by some new experimental data, we carry out a phenomenological analysis of D --> K pi decays including both Cabibbo favored and doubly Cabibbo suppressed modes. Two asymm…
Angular distribution asymmetry in tau^- --> pi^- pi^0 nu_tau decay in the two-Higgs-doublet model with large tan beta
Dao-Neng Gao
We study possible scalar type interactions in tau^- -->pi^- pi^0 nu_tau decay. One finds that an angular distribution asymmetry, A(s), can be induced from the interference between…
On the electron-positron energy asymmetry in K_L --> pi0 e+ e-
Dao-Neng Gao
Motivated by some new experimental and theoretical efforts, we update the theoretical analysis of the electron-positron energy asymmetry, which arises, in K_L --> pi0 e+ e-, from t…
Long-distance contribution to the forward-backward asymmetry in decays K+ --> pi+ l+ l-
Dao-Neng Gao
The long-distance contribution via the two-photon intermediate state to the forward-backward asymmetries in decays K+ --> pi+ l+ l- (l=e and mu) has been studied within the standar…
decay beyond the standard model
Ji-Hao Jiang, Dao-Neng Gao, Mu-Lin Yan
The decay is investigated beyond the standard model. Interestingly, the upper limit of the CP-conserving and CP-violating branching ratios of the decay, induced f…
Charge asymmetry in K+- --> π+-γγinduced by the electromagnetic penguin operators
Dao-Neng Gao
The CP-violating charge asymmetry in decays K+- --> π+- γγ, which is induced by the electromagnetic penguin operators, has been studied both in thestandard model and in its extensi…
