True Leptonium ( $l^{+} l^{-}$ ) Production in UPC Triphoton Interaction

Qi-Ming Feng, Qi-Wei Hu, Cong-Feng Qiao

True leptonium states ( $l^{+} l^{-}$ ) are compact pure QED systems, first theoretically predicted eight decades ago. Although considerable efforts have been devoted to their search, on…

NLO Corrections to Dimuonium Production in Photon-Photon Collision

Qi-Ming Feng, Si-Mao Guo, Qi-Wei Hu +7

Dimuonium ( $I^¼^{+} I^¼^{-}$ ) is one of the pure QED bound systems of leptons, together with positronium and ditauonium. The former had been observed in experiment in 1951, while the sea…

$J / I ¨ $ Polarization and $p_{T}$ distribution in $c c ˉ$ associated hadroproduction at $O (I^\pm_{s}^{5})$

Qi-Ming Feng, Cong-Feng Qiao

The quarkonium production in association with a heavy-quark pair of the same flavor was found plays an important role in various production schemes, let alone it provides a distinc…

NLO corrections to $J / I ¨ + c + c ˉ$ photoproduction

Qi-Ming Feng, Cong-Feng Qiao

Based on the factorization framework of nonrelativistic quantum chromodynamics, we study the associated $J / I ¨ + c + c ˉ$ photoproduction process at next-to-leading order in $I^\pm_{s}$ …
