Search for sterile neutrinos decaying into pions at the LHC
/ Dib, Claudio O. ; Kim, C. S. ; Neill, Nicolás A. ; Yuan, XingBo
We study the possibility to observe sterile neutrinos with masses in the range $5\text{}\text{}\mathrm{GeV}<{m}_{N}<20\text{}\text{}\mathrm{GeV}$ at the LHC, using the exclusive semileptonic modes involving pions, namely $W\to \ell N\to n\pi \ell \ell $ ($n=1,2,3$). [...]

/ Dib, Claudio O. ; Kim, C. S. ; Wang, Kechen
We present a search strategy for both Dirac and Majorana sterile neutrinos from the purely leptonic decays of W± → e± e± μ∓ν and μ± μ± e∓ν at the 14 TeV LHC. [...]

Probing new physics in B→Dℓ+ℓ decays by using angular asymmetries
/ Kim, C. S. ; Sahoo, Dibyakrupa
We present a fully general, modelindependent study of a few rare semileptonic B decays that get dominant contributions from W annihilation and W exchange diagrams, in particular B0→D¯0ℓ+ℓ , where ℓ=e,μ . [...]

Prompt atmospheric neutrino fluxes: perturbative QCD models and nuclear effects
/ Bhattacharya, Atri ; Enberg, Rikard ; Jeong, Yu ; Kim, C.S. ; et al
We evaluate the prompt atmospheric neutrino flux at high energies using three different frameworks for calculating the heavy quark production cross section in QCD: NLO perturbative QCD, k T factorization including low x resummation, and the dipole model including parton saturation. [...]

A model for pseudoDirac neutrinos: leptogenesis and ultrahigh energy neutrinos
/ Ahn, Y.H. ; Kang, Sin ; Kim, C.S.
We propose a model where sterile neutrinos are introduced to make light neutrinos to be pseudoDirac particles. [...]

Renormalization group evolution of neutrino parameters in presence of seesaw threshold effects and Majorana phases
/ Gupta, Shivani ; Kang, Sin Kyu ; Kim, C.S.
We examine the renormalization group evolution (RGE) for different mixing scenarios in the presence of seesaw threshold effects from high energy scale (GUT) to the low electroweak (EW) scale in the Standard Model (SM) and Minimal Supersymmetric Standard Model (MSSM). [...]

Radiative and seesaw threshold corrections to the S3 symmetric neutrino mass matrix
/ Gupta, Shivani ; Kim, C.S. ; Sharma, Pankaj
We systematically analyze the radiative corrections to the S3 symmetric neutrino mass matrix at high energy scale, say the GUT scale, in the charged lepton basis. [...]
