π++d→p+preaction between 18 and 44 MeV

Abstract

A study of the reaction ϩ ϩd→ pϩp has been performed in the energy range of 18-44 MeV. Total cross sections and differential cross sections at six angles have been measured at 15 energies with an energy increment of 1-2 MeV. This is the most systematic data set in this energy range. No structure in the energy dependence of the cross section has been observed within the accuracy of this experiment.

Differential cross sections measurement for thepp→dπ+reaction atBetigeri1, Bojowald2, Budzanowski3 et al. 2001Phys. Rev. C

“…This value is within the range of the Pasyuk et al data [8] and will thus allow to proof the importance of pp-wave interference in the anisotropy as already mentioned.…”

“…Near threshold data, appeared first in 1996 [6,7] and are in agreement with the SP96 solution. The newest data are from a measurement of the inverse reaction [8]. They are even below the Ritchie et al data [4], thus indicating the negligible effect of a 0 even in the interference term (see section III).…”

“…Furthermore, the new data of Ref. [8] show a much larger scattering than the threshold data, although the latter are from two different experiments. It is worth mentioning that in the measurement of the anisotropy, the luminosity cancels out.…”

Deuteron production and elliptic flow in relativistic heavy ion collisions

“…The cross sections for the inverse reactions M d → BB ′ are then determined from the detailed balance. Experimentally, the cross sections for both the reaction pp → dπ + [33,34] and the reaction π + d → pp [35,36,37] have been measured, and the former can be parameterized as…”

On the history of dibaryons and their final observation

“…A LAMPF experiment looking for very low-lying dibaryons in the π + d → pp reaction found no evidence for such states [126].…”
