Resolving the SELEX--LHCb Double-Charm Baryon Conflict: The Impact of Intrinsic Heavy-Quark Hadroproduction and Supersymmetric Light-Front Holographic QCD

TL;DR

This paper demonstrates that intrinsic heavy-quark mechanisms and supersymmetric light-front holographic QCD can reconcile conflicting experimental results on double-charm baryons from SELEX and LHCb, showing both are compatible.

Contribution

It introduces a QCD-based explanation for the experimental discrepancy and confirms the spectroscopy predictions with holographic QCD models.

Findings

Intrinsic heavy-quark production explains large $x_F$ heavy hadron yields.

SELEX and LHCb results are compatible under this framework.

Spectroscopy matches supersymmetric light-front holographic QCD predictions.

Abstract

In this paper we show that the intrinsic heavy-quark QCD mechanism for the hadroproduction of heavy hadrons at large $x_F$ can resolve the apparent conflict between measurements of double-charm baryons by the SELEX fixed-target experiment and the LHCb experiment at the LHC collider. We show that both experiments are compatible, and that both results can be correct. The observed spectroscopy of double-charm hadrons is in agreement with the predictions of supersymmetric light front holographic QCD.
