    • n quartet In music: A composition or movement for four solo parts, either vocal or instrumental, usually without accompaniment. Specifically, an instrumental work, usually for four stringed instruments, written in sonata form, and planned like a small symphony; a string-quartet. The quartet is the highest variety of chamber-music. It first reached its full development at the end of the eighteenth century.
    • n quartet A company of four singers or players who perform quartets. A mixed vocal quartet properly consists of a soprano (treble), an alto, a tenor, and a bass. A string-quartet consists of two violins, a viola, and a violoncello.

Hadronic Final States
First, each eigenvalue of Dcont will be replaced by a quartet, split by an amount which is expected to vanish in the continuum limit.17 The pairing of eigenvalues with opposite signs of the imaginary part still holds, now because of the U (1)e symmetry.
Rooted staggered fermions: good, bad or ugly?
The second difference between the spectra is that the zero mode of Dcont will become a quartet of non-zero modes, arranged into two pairs because of U (1)e.
Rooted staggered fermions: good, bad or ugly?
This ambiguity introduces a systematic error proportional to the fraction of configurations which have one or more eigenvalue quartets straddling the origin.
Rooted staggered fermions: good, bad or ugly?
In particular, one needs to look at the distribution of eigenvalues on the configurations produced in the actual simulations—do they lie in quartets, and how freq uently do quartets straddle the origin? The impact on the method using analytic continuation from imaginary m is less clear.
Rooted staggered fermions: good, bad or ugly?
This form assumes the splitting in eigenvalue quartets to be of O(a).
