We review the progress in atomic structure theory with a focus on superheavy elements and
their predicted ground state configurations important for an element's placement in the …

In this work we study the structures near 4.3 GeV in the J/ψ ϕ invariant mass spectra in B
meson decay process B+→ J/ψ ϕ K+ and two photon fusion process γ γ→ J/ψ ϕ. The Y …

Three-body systems with short-range interactions display universal features that have been
extensively explored in atomic physics, but apply to hadron physics as well. Systems …

We developed a numerical method, based on the Padé summation, to solve the covariant
spectator equation without partial wave decomposition, and applied it to the NN system. We …

Understanding pion production in nucleon-nucleon collisions near threshold has been a
challenge for the last decades. In particular, the reaction pp-> pppi0 is highly sensitive to …

We consider the covariant Spectator equation with a One Boson Exchange (OBE) kernel,
and apply it to the NN system. Relativistic effects such as retardation and negative-energy …

In our recent works we derived a chiral $ O (q^ 4) $ two-pion exchange nucleon-nucleon
potential (TPEP) formulated in a relativistic baryon (RB) framework, expressed in terms of …
