Using data collected on the psi(3770) resonance and near the Ds*+ Ds- peak production energy by the CLEO-c detector, we study the decays of the possible D->PP modes and report measurements of or upper limits on all branching fractions for Cabibbo-favored, singly-Cabibbo-suppressed, and doubly-Cabibbo-suppressed D->PP decays except modes involving K0L (and except D0->K+ pi-). We normalize with respect to the Cabibbo-favored D modes, D0->K- pi+, D+->K- pi+ pi+, and Ds+->K+ K0S.

  1. Compact $cs\bar{s}\bar{s}$ Tetraquarks in the Charm--Strange Sector: Mass Spectra, Rearrangement Decays and Regge Trajectories with $D_s$ Threshold Inputs

    hep-ph 2026-05 unverdicted novelty 5.0

    The authors compute mass spectra, rearrangement decays, and Regge trajectories for cs s-bar s-bar tetraquarks modeled as axial [cs][s-bar s-bar] systems in a Cornell potential framework with Ds threshold inputs.

  2. CP asymmetries in charged meson decay to two pions

    hep-ph 2026-05 unverdicted novelty 4.0

    CP asymmetries for B+ to pi+ pi0, D+ to pi+ pi0, and K+ to pi+ pi0 are estimated in the Standard Model at roughly 3 times 10 to the -3, 10 to the -5, and 10 to the -6 using a unified formalism for isospin violation.
