Three Body Bound State in Non-Commutative Space
M. Haghighat, F. Loran
The Bethe-Salpeter equation in non-commutative QED (NCQED) is considered for three-body bound state. We study the non-relativistic limit of this equation in the instantaneous appro…

Positronium Hyperfine Splitting in Non-commutative Space at the Order
M. Haghighat, S. M. Zebarjad, F. Loran
We obtain positronium Hyperfine Splitting owing to the non-commutativity of space and show that, in the leading order, it is proportional to where, is the parameter of n…

Scalar-Scalar Bound State in Non-commutative Space
M. Haghighat, F. Loran
Bethe-Salpeter equation in the non-commutative space for a scalar-scalar bound state is considered. It is shown that in the non-relativistic limit, the effect of spatial non-commut…
