Measurement of the double Dalitz decay $I^\cdot \to e^{+} e^{-} e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

The BESIII experiment measured the rare decay of the eta meson into two electron-positron pairs, determining its branching fraction to be about 2.6 × 10⁻⁵.

Demonstrating CBM Capabilities by $I^$ Baryon Reconstruction in Ni+Ni Collisions with the mCBM Experiment at SIS18 of GSI/FAIR

CBM Collaboration, A. Agarwal, Z. Ahammed +338

The Compressed Baryonic Matter (CBM) experiment at the upcoming Facility for Antiproton and Ion Research (FAIR) is a high-rate fixed-target experiment designed to investigate nucle…

Cross Section Measurements of $n ˉ p \to K^{+} K^{-} I ¨ ^{+} (I ¨ ^{0})$ via Antineutrons Produced by $J / I ¨ \to p I ¨ ^{-} n ˉ$ Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Based on a novel method for producing antineutrons via $J / I ¨ $ decays, we report a study of $n ˉ p$ inelastic scattering into final states containing kaons. The analysis uses $(1…

First Observation of $I^$ Hyperon Transverse Polarization in $I ¨ (3686) \to I^ I^ˉ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +687

Based on $(448.1 \pm 2.9) \times 1 0^{6}$ $I ¨ (3686)$ events collected with the BESIII detector at the BEPCII collider, we present the first observation of spin transverse polarization o…
