The MSSM confronts the precision electroweak data and the muon g − 2

- G. Cho, K. Hagiwara, Y. Matsumoto, D. Nomura
- Physics
- 10 April 2011

We update the electroweak study of the predictions of the Minimal Super-symmetric Standard Model (MSSM) including the recent results on the muon anomalous magnetic moment, the weak boson masses, and… Expand

Weak boson fusion production of supersymmetric particles at the CERN LHC

- G. Cho, K. Hagiwara, J. Kanzaki, T. Plehn, D. Rainwater, T. Stelzer
- Physics
- 9 January 2006

We present a complete calculation of weak boson fusion production of colorless supersymmetric particles at the LHC, using the new matrix element generator susy-madgraph . The cross sections are… Expand

Gravitational waves from compact binaries in post-Newtonian accurate hyperbolic orbits

- G. Cho, A. Gopakumar, M. Haney, Hyung-Mok Lee
- PhysicsPhysical Review D
- 6 July 2018

We derive from first principles third post-Newtonian (3PN) accurate Keplerian-type parametric solution to describe PN-accurate dynamics of non-spinning compact binaries in hyperbolic orbits. Orbital… Expand

Stochastic Dynamics of Infrared Fluctuations in Accelerating Universe

- G. Cho, Cook Hyun Kim, H. Kitamoto
- Physics
- 31 August 2015

We extend investigations of infrared dynamics in accelerating universes. In the presence of massless and minimally coupled scalar fields, physical quantities may acquire growing time dependences… Expand

Looking for $Z$ ' bosons in supersymmetric E(6) models through electroweak precision data

Cosmological gravitino problem confronts electroweak physics

A generic feature of gauge-mediated supersymmetry breaking models is that the gravitino is the lightest supersymmetric particle (LSP). In order not to overclose the universe, the gravitino LSP should… Expand

Gravitational radiation from inspiralling compact objects: Spin-spin effects completed at the next-to-leading post-Newtonian order

- G. Cho, Brian Pardo, Rafael A. Porto
- PhysicsPhysical Review D
- 26 March 2021

Using the gravitational potential and source multipole moments bilinear in the spins, first computed to next-to-leading order (NLO) in the post-Newtonian expansion within the effective field theory… Expand

Search for Kaluza-Klein gravitons in extra dimension models via forward detectors at the LHC

- G. Cho, T. Kono, K. Mawatari, Kimiko Yamashita
- Physics
- 19 March 2015

We investigate contributions of Kaluza-Klein (KK) graviton in extra dimension models to the process $pp \to p\gamma p \to p\gamma j X$, where a proton emits a quasireal photon and is detected by… Expand

From boundary data to bound states. Part III. Radiative effects

- G. Cho, Gregor Kalin, Rafael A. Porto
- PhysicsJournal of High Energy Physics
- 7 December 2021

Abstract
We extend the boundary-to-bound (B2B) correspondence to incorporate radiative as well as conservative radiation-reaction effects. We start by deriving a map between the total change in… Expand

Gravitational radiation from inspiralling compact objects: Spin effects to fourth Post-Newtonian order

- G. Cho, Rafael A. Porto, Zixin Yang
- Physics
- 13 January 2022

The linearand quadratic-in-spin contributions to the binding potential and gravitational-wave flux from binary systems are derived to next-to-next-to-leading order in the Post-Newtonian (PN)… Expand
