Fate of Gravitons in Warped Extra Dimension
Sanghyeon Chang, Masahiro Yamaguchi
Interaction of bulk gravitons to Standard Model particles is examined in the scenario of warped extra dimension. It is found that the length of the extra dimension is of physical i…

Axion in large extra dimension
Sanghyeon Chang, Shiro Tazawa, Masahiro Yamaguchi
We examine the axion model in the large extra dimensions scenario with TeV scale gravity. To obtain an intermediate-scale decay constant of the axion, the axion is assumed to live…

Transverse Spin Dependent Drell Yan in QCD to at Large (I). Virtual Corrections and Methods for the Real Emissions
Sanghyeon Chang, Claudio Coriano, John K. Elwood
We investigate the role of the transverse spin dependence in Drell Yan lepton pair production to NLO in QCD at parton level. In our analysis we deal with the large distributi…
