Can X(5568) be a tetraquark state?

Very recently, the D0 collaboration has reported the observation of a narrow structure, X(5568), in the decay process X(5568) → B sπ using the 10.4fb−1 data of pp̄ collision at √ s = 1.96 TeV. This structure is of great interest since it is the first hadronic state with four different valence quark flavors, b, s, u, d. In this work, we present a tetraquark interpretation of the X(5568). Based on...

It is a long discussed issue whether light scalar mesons have sizeable four-quark components. We present an exploratory study of this question using N f = 2+ 1+ 1 twisted mass lattice QCD. A mixed action approach ignoring disconnected contributions is used to calculate correlator matrices consisting of mesonic molecule, diquark-antidiquark and two-meson interpolating operators with quantum numb...

We present results of a 2+1+1 flavor twisted mass lattice QCD computation of the spectrum of D mesons and Ds mesons and of charmonium. Particular focus is put on the positive parity D states (so-called D∗∗ mesons) with quantum numbers JP = 0+, 1+ and 2+. Besides computing their masses we are also separating and classifying the two JP = 1 states according to the angular momentum/spin of their li...

Investigation of light and heavy tetraquark candidates using lattice QCD

We review the status of an ongoing long-term lattice investigation of the spectrum and structure of tetraquark candidates. We focus on the light scalar meson a0(980). First steps regarding the study of a possibly existing ccc̄c̄ tetraquark are also outlined.
