Deciphering triply heavy baryons in terms of QCD sum rules

TL;DR

This paper calculates the mass spectra of ground-state triply heavy baryons using QCD sum rules, proposing specific interpolating currents and including operators up to dimension six for accuracy.

Contribution

It introduces a systematic method to compute triply heavy baryon masses with a new configuration and detailed operator contributions in QCD sum rules.

Findings

Mass spectra of triply heavy baryons are computed.

Results are compared with other theoretical models.

Operators up to dimension six are included in the analysis.

Abstract

The mass spectra of ground-state triply heavy baryons are systematically unscrambled and computed in QCD sum rules. With a tentative $(QQ)-(Q')$ configuration for $QQQ'$, the interpolating currents representing the triply heavy baryons are proposed. Technically, contributions of the operators up to dimension six are included in operator product expansion (OPE). The numerical results are presented in comparison with other theoretical predictions.
