Examining the origin of dark matter mass at colliders
Minho Kim, Hye-Sung Lee, Myeonghun Park +1
As conventional dark matter scenarios have been probed extensively so far, the physics of a light dark matter charged under a new gauge group (dark gauge group) becomes one of new…
Precise top-quark mass from the diphoton mass spectrum
Sayaka Kawabata, Hiroshi Yokoya
We calculate the amplitude by including the bound-state effects near their mass threshold. In terms of the non-relativistic expansion of the amplitude, the LO c…
Effective field theory approach to heavy quark fragmentation
Michael Fickinger, Sean Fleming, Chul Kim +1
Using an approach based on Soft Collinear Effective Theory (SCET) and Heavy Quark Effective Theory (HQET) we determine the -quark fragmentation function from electron-positron a…
Fragmentation of a Jet with Small Radius
Lin Dai, Chul Kim, Adam K. Leibovich
In this paper we consider the fragmentation of a parton into a jet with small jet radius . Perturbatively, logarithms of can appear, which for narrow jets can lead to large…
Factorization of Jet Mass Distribution in the small limit
Ahmad Idilbi, Chul Kim
We derive a factorization theorem for the jet mass distribution with a given for the inclusive production, where is a large jet transverse momentum. Considering the…
A Model for Pseudo-Dirac Neutrinos: Leptogenesis and Ultra-High Energy Neutrinos
Y. H. Ahn, Sin Kyu Kang, C. S. Kim
We propose a model where sterile neutrinos are introduced to make light neutrinos to be pseudo-Dirac particles. It is shown how tiny mass splitting necessary for realizing pseudo-D…
Leptogenesis in supersymmetry with one violating coupling
Rathin Adhikari, Arnab Dasgupta
We have shown a new scenario of successful leptogenesis with one violating coupling and a relative Majorana phase playing the role of violation. This is in contrast to the…
Precise top mass determination using lepton distribution at LHC
Sayaka Kawabata
We present a new method to measure a theoretically well-defined mass of the top quark at the LHC. This method uses lepton energy distribution and has a boost-invariant nature. We p…
