The study of beta decay the charmed baryon provides unique insights into fundamental mechanism strong and electro-weak interactions. $\Lambda_c^+$, being lightest baryon, undergoes disintegration solely through charm quark weak decay. Its an ideal laboratory for investigating non-perturbative effects in quantum chromodynamics constraining parameters Cabibbo-Kobayashi-Maskawa matrix interaction theory. This article presents first observation Cabibbo-suppressed $\Lambda_c^+$ a neutron...
The decay $D\to K^-π^+$ is studied in a sample of quantum-correlated $D\bar{D}$ pairs, based on data set corresponding to an integrated luminosity 2.93\,fb$^{-1}$ collected at the $ψ(3770)$ resonance by BESIII experiment. asymmetry between $C\!P$-odd and $C\!P$-even eigenstate decays into $K^-π^+$ determined be ${\cal A}_{Kπ} = 0.132 \pm 0.011 0.007$, where first uncertainty statistical second systematic. This measurement update earlier study exploiting additional tagging modes, including...
Using 6.32~fb$^{-1}$ of $e^+e^-$ collision data recorded by the BESIII detector at center-of-mass energies between $4.178$ to $4.226$~GeV, we present first measurement decay $D_s^+\to f_0(980)e^+ν_e,\,f_0(980)\to π^0π^0$. The product branching fraction π^0π^0$ is measured be $(7.9\pm1.4_{\rm stat} \pm0.3_{\rm syst})\times 10^{-4}$, with a statistical significance $7.8σ$. Furthermore, upper limits on fractions f_0(500)e^+ν_e$ $f_0(500)\to and K_{S}^{0}K_{S}^{0}e^+ν_e$ are set $6.4\times...
