To do this, we first obtain the form factors defining these decay modes within the framework of QCD sum rules. Then, using the transition form factors, we compute the decay widths and branching fractions for all lepton channels and compare the results of our calculations with those obtained from other theoretical methods. We also estimate the branching ratios and the ratio of branching fractions at different leptonic channels to provide useful information for future experiments may be planned at different colliders. Such comparison will provide valuable information about the consistency/inconsistency of the Standard Model theory predictions with experimental data in weak semileptonic single heavy baryon decays.

Lepton flavor universality is a key prediction of the Standard Model of particle physics, and any violation of it immediately indicates the existence of new physics. Given the recent discrepancy of more than $$4\sigma $$ in charged current semileptonic $\textit{B}$ meson decays and the absence of evident signals at the Large Hadron Collider, independent cross-checks become invaluable. In this context, $$b \rightarrow c$$ semileptonic sum rules based on heavy quark symmetry are interesting, since they allow us to check the consistency of experimental results. In this paper, we report newly found sum rules among angular observables of mesonic and baryonic $$b\rightarrow c l {\overline{\nu }}$$ decays holding exactly in the large mass limit of heavy quarks. Moreover, we investigate corrections to the sum rule in realistic situations and discuss phenomenological implications.

In this work, we study the nonleptonic decays $$\Xi _{cc}^{++}\rightarrow \Xi _{c}^{(\prime )+}\pi ^{+}$$ with considering $$\Xi _{c}-\Xi _{c}^{\prime }$$ mixing. The relevant decay amplitudes are evaluated within the framework of nonrelativistic quark model, combining the baryon spatial wave functions adopted from solving the Schrödinger equation with a nonrelativistic potential. With the mixing angle ranging $$\theta \in (-18.2^{\circ },-14.3^{\circ }),$$ we successfully reproduce the measured ratio $$R={\mathcal {B}}[\Xi _{cc}^{++}\rightarrow \Xi _{c}^{\prime +}\pi ^{+}]/{\mathcal {B}}[\Xi _{cc}^{++}\rightarrow \Xi _{c}^{+}\pi ^{+}]$$ reported by the LHCb Collaboration. Furthermore, we estimate the branching fractions as $${\mathcal {B}}[\Xi _{cc}^{++}\rightarrow \Xi _{c}^{+}\pi ^{+}]=(3.2\sim 4.3)\%$$ and $${\mathcal {B}}[\Xi _{cc}^{++}\rightarrow \Xi _{c}^{\prime +}\pi ^{+}]=(4.2\sim 6.0)\%,$$ and the asymmetry parameters as $$\alpha [\Xi _{cc}^{++}\rightarrow \Xi _{c}^{+}\pi ^{+}]=(-0.80\sim -0.81)$$ and $$\alpha [\Xi _{cc}^{++}\rightarrow \Xi _{c}^{\prime +}\pi ^{+}]=(-0.61\sim -0.62).$$ The measurements of absolute branching fractions and asymmetry parameters by the ongoing LHCb and Belle II experiments will be helpful for further testing our numerical results and confirming the mixing angle.

This paper presents results on multiplicity fluctuations of positively and negatively charged hadrons as well as net-electric charge fluctuations measured in central Ar+Sc interactions at beam momenta 13$\textit{A}$, 19$\textit{A}$, 30$\textit{A}$, 40$\textit{A}$, 75$\textit{A}$, and 150 $$A\,\hbox {GeV}\!/\!c$$ . The fluctuation analysis is one of the tools to search for the predicted critical point of strongly interacting matter. Results are corrected for the experimental biases and quantified using cumulant ratios. In most instances, multiplicity and net-charge distributions appear narrower than the corresponding Poisson or Skellam distributions. Cumulant ratios are compared with the model predictions, which provide a qualitative description that aligns with observations for positively and negatively charged particles. The obtained results are also compared to earlier NA61/SHINE results from inelastic $\textit{p+p}$ interactions in the same analysis acceptance.
