Among all the hadrons, the ones that should be the simplest to analyze are those entirely composed by heavy quarks (and gluons). As it is evident from the spectra (e.g. by comparing the characteristic energy levels splitting with the value of the mass of the quarks in heavy quarkonium), these systems are nonrelativistic. Thus, they can be described in first approximation using a Schrödinger equ...

The concept of ecosystem services has been developed to address this link between ecosystems and human welfare. Since policy decisions are often evaluated through cost-benefit assessments, an economic...
