Interplay between Coulomb and nuclear forces in the low-energy three-body reaction p + 2Hµ → (pD) + µ− — •Renat A. Sultanov — 201 W. University Blvd., Department of Mathematics and Engineering, Odessa College, Wood Building of Math and Science (WOOD) Room 213, Odessa, TX 79764
Since p is an antibaryonic particle with the baryonic number B=−1, it would be interesting to discover the strong nuclear interaction between, for example, p and a proton, p. This is also known as the p-p interaction in a protonium atom - a bound state of the particles: Pn = (pp)α. The two-body system is also called antiprotonic hydrogen. Additionally, it would be useful to consider and compare results of similar Coulomb-nuclear atomic systems: p-D and p-T, where D=2H+ is the deuterium nucleus and T=3H+ is tritium. It is possible to prepare such atomic systems with the use of muons [1,2], for example, in the framework of the three-body reactions:

Here: µ− is a negative muon and α is the final atomic state of Pn or the pD atoms. In the current work, a detailed few-body treatment is carried out for these low-energy reactions with the use of a set of coupled few-body Faddeev equations and a modified close coupling approximation approach.
