We obtain positronium Hyperfine Splitting owing to the non-commutativity of space and show that, in the leading order, it is proportional to θα 6 where, θ is the parameter of non-commutativity. It is also shown that spatial non-commutativity splits the spacing between n = 2 triplet excited levels E(2 3 S 1) → E(2 3 P 2) which provides an experimental test(More)
In the context of the field theory we show that for particles with opposite non-commutativity, in QED, there is no correction for the two-body bound state at the tree level. Consequently, the Helium atom is considered in the non-commutative space. It is shown that the effects of spatial non-commutativity appear at the tree level and they are of the order α
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 approximation and derive the corresponding Schrödinger equation in non-commutative space. It is shown that the experimental data for Helium atom puts an upper bound on the magnitude of(More)
Total mercury in muscle and liver of Oriental sole from the largest inlet in the Persian Gulf was evaluated. Fish were collected from three channels of Moses Inlet near a chlor-alkali plant. Ahamdi and Jafari channels were closest to this plant and Ghanam was farther away. We sampled in August 2007 and February 2008. The overall estimated marginal mean for(More)
We derive Spinless Salpeter equation for the positronium using the NRQED La-grangian. Consequently, we consider the Spinless Salpeter wavefunction instead of the Schrodinger wavefunction to show that the NRQED calculation can be done easier. We also discuss that the singularity of the Spinless Salpeter wavefunction at the origin is necessary to cancel the(More)
In the current world, sports produce considerable statistical information about each p layer, team, games, and seasons. Traditional sports science believed science to be o wned by experts, coaches, team managers, and analyzers. However, sports organizations have recently realized the abundant science available in their data and sought to take advantage of(More)
