An important study in quantum mechanics is the study of scattering. By employing scattering, it is possible to find new states that can be bound or short-lived. In this paper, We will formally derive the scattering amplitude for scattering on the potential and express it with a phase shift. Although this approach is quite restrictive, it still produces important results. It renders information on the interaction between particles and reveals properties of bound states and resonances. After the theoretical formalism, We will give some examples of states studied numerically and experimentally. Although scattering is present in many fields of physics, We will focus on examples from hadron particle physics.
Pomemben del kvantne mehanike je raziskava sipanja. Preko uporabe sipanja kot orodja, je možno najti nova stanja, ki so lahko vezana ali kratkoživa. V tem članku, bomo formalno izpeljali sipalno amplitudo za sipanje na potencialni jami in jo zapisali preko faznega zamika. Čeprav je pristop omejevalen, prinese s seboj nekaj pomembnih rezultatov. Razkrije informacijo o interakciji med delci in prikaže lastnosti vezanih stanj ter resonanc. Po teoretičnem formalizmu bomo podali nekaj primerov stanj, ki jih lahko študiramo numerično in eksperimentalno. Čeprav je sipanje prisotno v skoraj vseh območjih fizike, se bomo osredotočili na primere iz hadronske fizike delcev.
