This package contains effective formulas to describe the mass of heavy-light pseudoscalar mesons. The effective formulas are generated by simplifying the results of the Fermilab Lattice, MILC, and TUMQCD project on determination of the up-, down-, strange-, charm-, and bottom-quark masses from lattice-QCD simulations with four flavors of dynamical quarks. The project employes the MRS mass and a combination of three effective field theories (EFTs) for statistical analysis of lattice-QCD data. (A short description of the project can be found in Prog.Part.Nucl.Phys; see chapter 7.)
Four heavy-light pseudoscalar mesons are supported: D, Ds, B, Bs.
- How to use:
>>> from meson_mass import Model >>> Model('D').predict([0.1, 0.2, 0.3]) >>> array([1876.81(97), 1890.8(1.3), 1904.6(1.5)], dtype=object)
Command line interface is available too:
$ meson_mass.py --model D 0.1 0.2 0.3
$ [1876.81(97) 1890.8(1.3) 1904.6(1.5)]What to cite:
The theoretical framework for determination of the up-, down-, strange-, charm-, and bottom-quark masses is developed in three references: SChPT, Renormalon, and MRS mass. Please consider citing them if you use this package.
