Light scalar quarkonia from QCD Laplace sum rule at higher order

R. M. Albuquerque, S. Narison, D. Rabetiarivony

We review our estimations on the light scalar $\bar{q}q$, $(\bar{q}{q}^{\prime })(\overline{q^{\prime }}q)$ and $\overline{q{q}^{\prime }}q{q}^{\prime }$ ($q,q^{\prime }\equiv u,d,s$) states from relativistic Laplace sum rule (LSR) with…
