Observation of the leptonic decay $D^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +479

We report the first observation of $D^{+} \to τ^{+} ν_{τ}$ with a significance of $5.1 σ$ . We measure ${\cal B}(D^+\toτ^+ν_τ) = (1.20\pm0.24_{\text{stat.}}\pm0.12_{\text{syst.}})\times10^{-3…

Measurement of the mass difference and the binding energy of the hypertriton and antihypertriton

STAR Collaboration, J. Adam, L. Adamczyk +340

According to the CPT theorem, which states that the combined operation of charge conjugation, parity transformation and time reversal must be conserved, particles and their antipar…

Complete measurement of $Λ$ electromagnetic form factors

M. Ablikim, M. N. Achasov, P. Adlarson +475

The exclusive process $e^{+} e^{-} \to Λ Λ ˉ$ , with $Λ \to p π^{-}$ and $Λ ˉ \to p ˉ π^{+}$ , has been studied at $s =$ 2.396 GeV for measurement of the $Λ$ electric and mag…
