The structure, mixing angle, mass and couplings of the light scalar $f_{0} (500)$ and $f_{0} (980)$ mesons

S. S. Agaev, K. Azizi, H. Sundu

The mixing angle, mass and couplings of the light scalar mesons $f_{0} (500)$ and $f_{0} (980)$ are calculated in the framework of QCD two-point sum rule approach by assuming that they a…

On the mass and decay constant of the P-wave ground and radially excited $h_{c}$ and $h_{b}$ axial-vector mesons

K. Azizi, J. Y. Sungu

The mass and decay constant of the heavy quarkonia $h_{Q} (1 P)$ and $h_{Q} (2 P)$ (Q = b, c) with quantum numbers $J^{P C} = 1^{+-}$ are calculated in the framework of the two-point QCD…

The role of the triangle singularity in $Λ (1405)$ production in the $π^{-} p \to K^{0} π Σ$ and $pp \to p K^{+} π Σ$ processes

M. Bayar, R. Pavao, S. Sakai +1

We have investigated the cross section for the $π^{-} p \to K^{0} π Σ$ and $pp \to p K^{+} π Σ$ reactions paying attention to a mechanism that develops a triangle singularity. Th…
