Title: Perturbative corrections to heavy quark-diquark symmetry predictions for doubly heavy baryon hyperfine splittings

Abstract

Doubly heavy baryons ($$\textit{QQq}$$) and singly heavy antimesons ($$\bar{Q}q$$) are related by the heavy quark-diquark (HQDQ) symmetry because in the $$m_Q → ∞$$ limit, the light degrees of freedom (d.o.f.) in both the hadrons are expected to be in identical configurations. Hyperfine splittings of the ground states in both systems are nonvanishing at $$O(1/m_Q)$$ in the heavy quark mass expansion, and HQDQ symmetry relates the hyperfine splittings in the two sectors. In this paper, working within the framework of nonrelativistic QCD (NRQCD), we point out the existence of an operator that couples four heavy quark fields to the chromomagnetic field with a coefficient that is enhanced by a factor from Coulomb exchange. This operator gives a correction to doubly heavy baryon hyperfine splittings that scales as $$1/m^2_Q × α_S/r$$, where $$\textit{r}$$ is the separation between the heavy quarks in the diquark. This correction can be calculated analytically in the extreme heavy quark limit in which the potential between the quarks in the diquark is Coulombic. In this limit, the correction is $$O(α^2_s/m_Q)$$ and comes with a small coefficient. For values of $$α_s$$ relevant to doubly charm and doubly bottom systems, the correction to the hyperfine splittings in doubly heavy baryons is only a few percent or smaller. We also argue that nonperturbative corrections to the prediction for the hyperfine splittings are suppressed by $$Λ^2_{\text{QCD}}/m^2_Q$$ rather than $$Λ_{\text{QCD}}/m_Q$$. Corrections should be ≈10% in the charm sector and smaller in heavier systems.

Doubly Heavy Baryons, Heavy Quark-DiQuark Symmetry and NRQCD

In the heavy quark limit, properties of heavy mesons and doubly heavy baryons are related by heavy quark-diquark symmetry. This problem is reanalyzed in the framework of Non-Relativistic QCD (NRQCD). We introduce a novel method for deriving Potential NRQCD (pNRQCD) Lagrangians for composite fields from vNRQCD, which contains quarks and antiquarks as explicit degrees of freedom and maintains manifest power counting in the velocity via a label formalism. A Hubbard-Stratonovich transformation is used to eliminate four quark interactions in vNRQCD and then quarks and antiquarks are integrated out to get effective Lagrangians for composite fields.

Doubly heavy baryons and quark-diquark symmetry in quenched and partially quenched chiral perturbation theory

Journal Article Mehen, Thomas ; Tiburzi, Brian C

We extend the chiral Lagrangian with heavy quark-diquark symmetry to quenched and partially quenched theories. These theories are used to derive formulae for the chiral extrapolation of masses and hyperfine splittings of doubly heavy baryons in lattice QCD simulations. A quark-diquark symmetry prediction for the hyperfine splittings of heavy mesons and doubly heavy baryons is rather insensitive to chiral corrections in both quenched and partially quenched QCD. Extrapolation formulae for the doubly heavy baryon electromagnetic transition moments are also determined for the partially quenched theory.

Isospin Splittings of Doubly Heavy Baryons

Journal Article Brodsky, Stanley J ; /SLAC ; Guo, Feng-Kun ; ... - Phys.Lett.B698:251-255,2011

The SELEX Collaboration has reported a very large isospin splitting of doubly charmed baryons. We show that this effect would imply that the doubly charmed baryons are very compact. One intriguing possibility is that such baryons have a linear geometry Q-q-Q where the light quark q oscillates between the two heavy quarks Q, analogous to a linear molecule such as carbon dioxide. However, using conventional arguments, the size of a heavy-light hadron is expected to be around 0.5 fm, much larger than the size needed to explain the observed large isospin splitting. Assuming the distance between two heavy quarks ismore »« less
