Resummation of threshold double logarithms in quarkonium fragmentation functions
Hee Sok Chung, U-Rae Kim, Jungil Lee
We develop a formalism for resumming threshold double logarithms that appear in fragmentation functions for production of heavy quarkonia. Threshold singularities appear in fixed-o…
Resummation of threshold double logarithms in inclusive production of heavy quarkonium
Hee Sok Chung, U-Rae Kim, Jungil Lee
We resum threshold double logarithms in inclusive production of heavy quarkonium that arise from singularities near the boundary of phase space. This resolves the catastrophic fail…
Resummation of threshold double logarithms in hadroproduction of heavy quarkonium
Hee Sok Chung, U-Rae Kim, Jungil Lee
We resum threshold double logarithms that appear in inclusive production of heavy quarkonium. This resolves the catastrophic failure of fixed-order perturbation theory where quarko…
Scalar dark matter multiplet of global symmetry
U-Rae Kim, Jungil Lee, Soo-hyeon Nam
We study two types of models involving a scalar dark matter multiplet of global symmetry. These models are distinguished by the absence (Type I) or presence (Type II) of a s…
