First Observation of $Λ$ Hyperon Transverse Polarization in $ψ (3686) \to Λ Λ ˉ$

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

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

Measurement of the space-like $π^{0}$ transition form factor

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

Based on $2.93 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at a center-of-mass energy of $3.773 GeV$ , the two-photon fusion process $e^+e^-\t…

Exploring Gradient-Guided Masked Language Model to Detect Textual Adversarial Attacks

Xiaomei Zhang, Zhaoxi Zhang, Yanjun Zhang +4

Textual adversarial examples pose serious threats to the reliability of natural language processing systems. Recent studies suggest that adversarial examples tend to deviate from t…

Search for $η_{1} (1855)$ in $χ_{c J} \to η η η^{'}$ decays

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

Based on a sample of $2.7 \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, an analysis of the decay $ψ(3686)\toγχ_{cJ}, χ_{cJ}\toηηη…
