The doubly charmed pseudoscalar tetraquarks T-cc(;(s)over-bar(s)over-bar)++ and T-cc(;(d)over-bar<)(s()over bar)>(++)
Agaev, Shahin S.; Azizi, Kazem; Barsbay, Birten; Sundu, Hayriye (Elsevier, 2019-02)The mass and coupling of the doubly charmed J(P) = 0(-) diquark-antidiquark states T-cc (s) over bar(s) over bar(++) and T-cc;(d) over bar<(s)over (++)(bar)(>) that bear two units of the electric charge are calculated by ... -
Light scalar K-0* (700) meson in vacuum and a hot medium
Azizi, Kazem; Barsbay, Birten; Sundu, Hayriye (American Physical Society, 2019)The K-0* (700) meson appears as the lightest strange scalar meson in Particle Data Group (PDG). Although there were a lot of experimental and theoretical efforts to establish this particle and determine its properties and ... -
Mass and residue of Lambda(1405) as hybrid and excited ordinary baryon
Azizi, Kazem; Sundu, Hayriye; Barsbay, Birten (Springer, 2018-03)The nature of the Lambda(1405) has been a puzzle for decades, whether it is a standard three-quark baryon, a hybrid baryon or a baryon-meson molecule. More information on the decay channels of this particle and its strong, ... -
Probing an axial-vector tetraquark Zs via its semileptonic decay Zs → X(4274) l¯ νl
Sundu, Hayriye; Barsbay, Birten; Agaev, Shahin S.; Azizi, Kazem (Springer, 2018-07)The semileptonic decays of the open charm-bottom axial-vector tetraquark Zs= [cs] [b¯ s¯] to X(4274) l¯ νl , l= e, μ, τ are explored by means of the QCD three-point sum rule method. Both Zs and X(4274) = [cs] [c¯ s¯] are ... -
Resonance X(5568) as an exotic axial-vector state
Agaev, Shahin S.; Azizi, Kazem; Barsbay, Birten; Sundu, Hayriye (Springer, 2017-01-23)The mass and meson-current coupling constant of the resonance X(5568), as well as the width of the decay X(5568) -> B-s*pi are calculated by modeling the exotic X(5568) resonance as a diquark-antidiquark state X- b = ... -
Weak decays of the axial-vector tetraquark Tbb;(u)over-bar(d)over-bar(-)
Agaev, Shahin S.; Azizi, Kazem; Barsbay, Birten; Sundu, Hayriye (American Physical Society, 2019-02)The weak decays of the axial-vector tetraquark T-bb;(u) over bar(d) over bar(-) to the scalar state Z(bc;(u) over bar(d) over bar)(0) are investigated using the QCD three-point sum rule approach. In order to explore the ...
