As the mixing states of the pseudoscalar singlet and octet, eta/eta' offer an important laboratory to test the fundamental symmetries and to search for new physics beyond the Standard Model. In this talk, I will give an overview of the recent related progress and insights on eta/eta' decays at BESIII, KLOE/KLOE2. In addition, I will also include the prospect in eta/eta' decays that could be...
Lattice data for the electromagnetic isospin-breaking correction to the hadronic vacuum polarization contribution (HVP) to the anomalous magnetic moment of the muon are analyzed in the framework of a phenomenological hadronic model. We find a steep chiral dependence and non-negligible finite-volume effects, which are quantified within the model.
The BESIII experiment has collected 20.3 $fb^{-1}$ and 7.33 $fb^{-1}$ of e+e- collision data at center-of-mass energies of 3.773 GeV and 4.128-4.226 GeV, respectively.
This presentation will provide an overview of recent studies using (semi)-leptonic D decays at BESIII. We will present the first experimental investigation of $D_s^{*+} \to l^+ \nu$ decays, along with improved measurements of...
With the large datasets from $e^+e^-$ annihilation at the $J/\psi$ resonance collected by the BESIII experiment, multidimensional analyses leveraging polarization and entanglement can provide new insights into the hadronic structure of semileptonic decays. Recent studies at BESIII enable the measurement of form factor ratios of (anti)hyperons in the decays $J/\psi\to\Lambda\bar{\Lambda}$ and...
We compute the Form Factors of both neutral and charged pion using a non-perturbative running of the strong-coupling constant αs obtained using a double-dilaton Holographic QCD model. These form factors remain poorly understood in the intermediate-energy region, which marks the transition between low- and high-energy physics. In particular, experimental data for the neutral pion Form Factor...
