Title: On HQET and NRQCD operators of dimension 8 and above

Abstract

Effective field theories such as Heavy Quark Effective Theory (HQET) and Non Relativistic Quantum Chromo-(Electro-) dynamics NRQCD (NRQED) are indispensable tools in controlling the effects of the strong interaction. The increasing experimental precision requires the knowledge of higher dimensional operators. We present a general method that allows for an easy construction of HQET or NRQCD (NRQED) operators that contain two heavy quark or non-relativistic fields and any number of covariant derivatives. As an application of our method, we list these terms in the 1/M⁴ NRQCD Lagrangian, where M is the mass of of the spin-half field.

Decay b{yields}(cc)s in the leading logarithm approximation

Journal Article Bobeth, Christoph ; Grinstein, Benjamin ; Savrov, Mikhail ; ... - Physical Review. D, Particles Fields

We consider an effective field theory for the nonleptonic decay in which a heavy quark decays into a pair of a heavy quark and antiquark having a small relative velocity and one relativistic (massless) quark. This effective theory is a combination of heavy quark effective theory (HQET), soft-collinear effective theory (SCET), and a covariant modification of nonrelativistic QCD (NRQCD). In the leading logarithm approximation the effective theory decay amplitude factorizes into the product of matrix elements of heavy-to-heavy and heavy-to-light currents. We discuss a possibility of factorization beyond the leading logarithm approximation and find it doubtful. The Wilson coefficients ofmore »« less

Doubly Heavy Baryons, Heavy Quark-DiQuark Symmetry and NRQCD

Journal Article Fleming, Sean ; Mehen, Thomas

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. This method is used tomore »« less

Quarkonium in-medium properties from realistic lattice NRQCD

Journal Article Kim, Seyong ; Petreczky, Peter ; Rothkopf, Alexander - Journal of High Energy Physics (Online)

Here, we present the final results of our high statistics study on the properties of bottomonium and charmonium at finite temperature. We focus on the temperature range around the crossover transition 150 ≤ T ≤ 410MeV, relevant for current heavy ion collision experiments. The QCD medium degrees of freedom, which consist of dynamical u,d, and s quarks and gluons are captured by realistic state-of-the art (m_π ≈ 161MeV) lattice QCD simulations of the HotQCD collaboration. For the heavy quarks we deploy the non-relativistic effective field theory of QCD, NRQCD. The in-medium properties of quarkonium are deduced from their spectral functions,more »« less

Strong coupling constant and quark masses from lattice QCD

Journal Article Komijania, Javad ; Petreczky, Peter ; Weber, Johannes Heinrich - Progress in Particle and Nuclear Physics

In this paper, we review lattice determinations of the charm- and bottom-quark masses and the strong coupling constant obtained by different methods. We explain how effective field theory approaches, such as Non-Relativistic QCD (NRQCD), potential Non-Relativistic QCD (pNRQCD), Heavy Quark Effective Theory (HQET) and Heavy Meson rooted All- Staggered Chiral Perturbation Theory (HMrASχPT) can help in these determinations. After critically reviewing different lattice results we determine lattice world averages for the strong coupling constant,more »« less

Lattice NRQCD study on in-medium bottomonium spectra using a novel Bayesian reconstruction approach

Journal Article Kim, Seyong ; Petreczky, Peter ; Rothkopf, Alexander - AIP Conference Proceedings

We present recent results on the in-medium modification of S- and P-wave bottomonium states around the deconfinement transition. Our study uses lattice QCD with N{sub f} = 2 + 1 light quark flavors to describe the non-perturbative thermal QCD medium between 140MeV < T < 249MeV and deploys lattice regularized non-relativistic QCD (NRQCD) effective field theory to capture the physics of heavy quark bound states immersed therein. The spectral functions of the {sup 3}S{sub 1} (ϒ) and {sup 3}P{sub 1} (χ{sub b1}) bottomonium states are extracted from Euclidean time Monte Carlo simulations using a novel Bayesian prescription, which provides highermore »« less
