Measurement of the branching fractions of the singly Cabibbo-suppressed decays Λ c + → p η $$ {\Lambda}_{\textrm{c}}^{+}\to \textrm{p}\eta $$ and Λ c + → p ω $$ {\Lambda}_{\textrm{c}}^{+}\to \textrm{p}\omega $$

open access: yesJournal of High Energy Physics, 2023
Based on 4.5 fb −1 e + e − collision data collected with BESIII detector at seven energy points between 4.600 and 4.699 GeV, the branching fractions for Λ c + → pη $$ {\Lambda}_c^{+}\to p\eta $$ and Λ c + → pω $$ {\Lambda}_c^{+}\to p\omega $$ were ...

Probing for new physics with rare charm baryon (Λc, Ξc, Ωc) decays

open access: yesJournal of High Energy Physics, 2021
We analyze rare charm baryon decays within the standard model and beyond. We identify all null test observables in unpolarized Λc→ pℓ+ℓ−, ℓ = e, μ decays, and study the new physics sensitivities.

Tau Physics Opportunities at the Super Tau-Charm Facility [PDF]

open access: yesInternational Journal of Modern Physics A
The super tau-charm facility will provide excellent conditions to perform a high-precision investigation of the tau-lepton properties: very high statistics, controllable systematics and low backgrounds. An overview of the broad physics program that could

Charm Physics: another route towards New Physics [PDF]

open access: yes, 2018
We summarize recent results for charm physics. These results span several categories: charm mixing, indirect (time-dependent) CP violation, direct (time-integrated) CP violation, T violation, semileptonic and leptonic decays, and decays of charm baryons.

Charm (-onium) physics at PANDA

open access: yesProceedings of 10th International Workshop on Charm Physics — PoS(CHARM2020), 2021
The new Facility for Antiproton and Ion Research (FAIR) is under construction at GSI in Darmstadt (Germany). The PANDA experiment represents the central part of the hadron physics programme, addressing a wide range of topics in hadron structure and ...

The PANDA experiment: physics goals and experimental setup

open access: yesEPJ Web of Conferences, 2014
PANDA (antiProton ANnihilation at DArmstadt) is an experiment that will run at the GSI laboratory, Darmstadt, Germany, in 2019. A high intensity antiproton beam with momentum up to 15 GeV/c will collide on a fixed proton target (pellet target or jet ...

Constraining |Vcs| and physics beyond the Standard Model from exclusive (semi)leptonic charm decays [PDF]

open access: yesJournal of High Energy Physics
We study the available data on exclusive leptonic and semileptonic c → sℓ+ν decays within the Standard Model and beyond. Our analysis accounts for theory correlations between the relevant hadronic matrix elements through application of dispersive bounds.

Λ c + $$ {\Lambda}_c^{+} $$ polarimetry using the dominant hadronic mode

open access: yesJournal of High Energy Physics, 2023
The polarimeter vector field for multibody decays of a spin-half baryon is introduced as a generalisation of the baryon asymmetry parameters. Using a recent amplitude analysis of the Λ c + $$ {\Lambda}_c^{+} $$ → pK − π + decay performed at the LHCb ...
