We construct a new global optical model potential to describe the elastic scattering of 12C.The experiment-al data of elastic-scattering angular distributions a
According to a corrected dispersion relation proposed in the study on the string theory and quantum grav-ity theory,the Rarita-Schwinger equation was precisely
Motivated by the problem of expanding the single-trace tree-level amplitude of Einstein-Yang-Mills the-ory to the BCJ basis of Yang-Mills amplitudes,we present
