“…The mass of the pseudoscalar B c meson is M Bc = (6.277 ± 0.006) GeV from the Particle Data Group [4], while the calculations based on the nonrelativistic renormalization group indicate that [17]. We can tentatively take the continuum threshold parameters as s 0…”

“…GeV is much larger than other theoretical calculations [7,8,9,10,11,12,13,17,18]. Those studies based on the QCD sum rules were preformed before the pseudoscalar B c mesons were observed by the CDF collaboration, the predictions should be updated.…”

“…The excited states can undergo radiative or hadronic transitions to the ground state pseudoscalar B c mesons, which decay weakly. There have been several theoretical works on the mass spectroscopy of the B c mesons, such as the relativized (or relativistic) quark model with an special phenomenological potential [7,8,9,10], the nonrelativistic quark model with an special phenomenological potential [11,12,13,14], the semi-relativistic quark model using the shifted large-N expansion [15], the perturbative QCD [16], the nonrelativistic renormalization group [17], the lattice QCD [18,19], etc.…”

In this article, we carry out the operator product expansion by including the next-to-leading-order perturbative contributions, study the masses and decay constants of the vector and axialvector B c mesons with the QCD sum rules, and make reasonable predictions for the masses and decay constants, furthermore, we calculate the leptonic decay widths.…”

In this article, we study the vector and axialvector Bc mesons with the QCD sum rules, and make reasonable predictions for the masses and decay constants, then calculate the leptonic decay widths. The present predictions for the masses and decay constants can be confronted with the experimental data in the future. We can also take the masses and decay constants as basic input parameters and study other phenomenological quantities with the three-point vacuum correlation functions via the QCD sum rules.

“…Although in the decay B * c → B c γ, the soft photon γ is difficult to detect so as to reconstruct the B * c state, the partial decay width Γ(B * c → B c γ) is about 100 eV from the QCD sum rules [35]. The mass splitting M B * c − M Bc from the nonrelativistic renormalization group is about 46 ± 15 +13 −0.11 MeV [36], which can be taken into account in the uncertainty analysis.…”

In this article, we construct the diquark-antidiquark type current operators to study the axialvector Bc-like tetraquark states with the QCD sum rules. In calculations, we take the energy scale formula as a powerful constraint to choose the ideal energy scales of the QCD spectral densities and add detailed discussions to illustrate why we take the energy scale formula to improve the QCD sum rules for the doubly heavy tetraquark states. The predicted masses M Zb c (1 +− ) = 7.30 ± 0.08 GeV and M Zb c (1 ++ ) = 7.31 ± 0.08 GeV lie between the conventional 2P and 3P Bc states with J P = 1 + from the potential quark models, which is a typical feature of the diquark-antidiquark type Bc-like tetraquark states.

Coulomb artifacts and bottomonium hyperfine splitting in lattice NRQCD

Abstract:We study the role of the lattice artifacts associated with the Coulomb binding effects in the analysis of the heavy quarkonium within lattice NRQCD. We find that a "naïve" perturbative matching generates spurious linear Coulomb artifacts, which result in a large systematic error in the lattice predictions for the heavy quarkonium spectrum. This effect is responsible, in particular, for the discrepancy between the recent determinations of the bottomonium hyperfine splitting in the radiatively improved lattice NRQCD [1,2]. We show that the correct matching procedure which provides full control over discretization errors is based on the asymptotic expansion of the lattice theory about the continuum limit, which gives M Υ(1S) − M η b (1S) = 52.9 ± 5.5 MeV [1].
