Effects of odderon spin on helicity amplitudes in elastic scattering
In recent years, the discovery of the odderon, a colorless -odd gluonic
compound, has been confirmed in the TOTEM and D0 collaborations. However, the
spin quantum number of the odderon remains unidentified. In this work, we aim
to attribute a spin of to the odderon in elastic scattering by
calculating the helicity amplitudes and the corresponding complex parameter
, the ratio of helicity's single-flip to non-flip amplitudes, for the
spin-3 tensor odderon with the standard spin-2 tensor pomeron exchanges. Then,
we apply these results to the constraints obtained from the STAR experiment at
RHIC. By comparing to the contributions of the spin-1 vector odderon and spin-2
tensor pomeron, we demonstrate that the spin-3 tensor odderon, i.e. ,
provides a better explanation for the observable in elastic scattering.Comment: 11 pages, 2 figure
Effects of odderon spin on helicity amplitudes in
In recent years, the discovery of the odderon, a colorless C-odd gluonic compound, has been confirmed in the TOTEM and D0 collaborations. However, the spin quantum number of the odderon remains unidentified. In this work, we aim to attribute a spin of to the odderon in pp elastic scattering by calculating the helicity amplitudes and the corresponding complex parameter , the ratio of helicity’s single-flip to non-flip amplitudes, for the spin-3 tensor odderon with the standard spin-2 tensor pomeron exchanges. Then, we apply these results to the constraints obtained from the STAR experiment at RHIC. By comparing to the contributions of the spin-1 vector odderon and spin-2 tensor pomeron, we demonstrate that the spin-3 tensor odderon, i.e. , provides a better explanation for the observable in pp elastic scattering
