Measurements of the Absolute Branching Fraction of the Semileptonic Decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ and the Axial Charge of the $Ξ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we study the semileptonic decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ for the first time at an electron-…

Evidence for the semileptonic decays $Λ_{c}^{+} \to Σ^{\pm} π^{\mp} e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

Using $4.5 f b^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at center-of-mass energies between $4.600$ and $4.699 G e V$ , we search for the semileptonic decays…

$f_{K} / f_{π}$ in iso-symmetric QCD and the CKM matrix unitarity

Alessandro Conigli, Julien Frison, Alejandro Sáez

We present lattice results for $f_{K} / f_{π}$ in the iso-symmetric limit of pure QCD (isoQCD) with $N_{f} = 2 + 1$ flavours, along with a determination of $∣ V_{u s} ∣/∣ V_{u d} ∣$ and a study on t…

From closed shells to open shells: Coupled-cluster calculations of atomic nuclei

F. Marino, F. Bonaiti, P. Demol +6

Coupled-cluster theory is a powerful tool for first-principles calculations of atomic nuclei, enabling accurate predictions of nuclear observables across the Segrè chart. While cou…

Search for the decays $X (3872) \to K_{S}^{0} K^{\pm} π^{\mp}$ and $K^{*} (892) K ˉ$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using a 10.9 fb $^{- 1}$ data sample collected by the BESIII detector at center-of-mass energies from 4.16 to 4.34 GeV, we search for the charmless decays $X(3872) \to K_{S}^{0}K^{\p…

Search for a solar-bound axion halo using the Global Network of Optical Magnetometers for Exotic physics searches

Tatum Z. Wilson, Derek F. Jackson Kimball, Samer Afach +50

We report on a search for a gravitationally bound solar axion halo using data from the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), a worldwide arra…
