Analytical $O (α_{s})$ corrections to the beam frame double-spin density matrix elements of $e^{+} e^{-} \to t t ˉ$

L. Kaldamäe, S. Groote, J. G. Körner

We provide analytical results for the $O (α_{s})$ corrections to the double-spin density matrix elements in the reaction $e^{+} e^{-} \to t t ˉ$ . These concern the elements $l l$ , $l t$ , $l…

Four-quark structure of Zc(3900), Z(4430) and Xb(5568) states

Fabian Goerke, Thomas Gutsche, Mikhail A. Ivanov +3

We examine the four-quark structure of the recently discovered charged $Z_{c} (3900)$ , $Z (4430)$ , and $X_{b} (5568)$ states. We calculate the widths of the strong decays $Z_c^+ \to J/ψπ^…

Nucleon tensor form factors in a relativistic confined quark model

Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +2

We present results for the isotriplet and isosinglet tensor form factors of the nucleon in the relativistic confined quark model. The model allows us to calculate not only their no…

Isospin-violating strong decays of scalar single-heavy tetraquarks

Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +1

We present a study of the isospin-violating one-pion strong decays of single heavy tetraquarks $X_{Q} = X (s q q ˉ Q ˉ)$ , $Q = c, b$ , and $q = u, d$ with spin-parity $J^{P} = 0^{+}$ . We…

Analyzing new physics in the decays $B ˉ^{0} \to D^{(*)} τ^{-} ν ˉ_{τ}$ with form factors obtained from the covariant quark model

Mikhail A. Ivanov, Jürgen G. Körner, Chien-Thang Tran

We study possible New Physics (NP) effects in the exclusive decays $B ˉ^{0} \to D^{(*)} τ^{-} ν ˉ_{τ}$ . We extend the Standard Model (SM) by taking into account right-handed vec…
