Light Higgsinos for electroweak naturalness in mirage-mediated high-scale supersymmetry

1 code implementation24 Nov 2020 Kwang Sik Jeong, Chan Beom Park

Mirage mediation realized in the Kachru-Kallosh-Linde-Trivedi (KKLT) flux compactification can naturally suppress the up-type Higgs soft mass at low energy scales.

YAM2: Yet another library for the $M_2$ variables using sequential quadratic programming

3 code implementations30 Jul 2020 Chan Beom Park

The $M_2$ variables are devised to extend $M_{T2}$ by promoting transverse masses to Lorentz-invariant ones and making explicit use of on-shell mass relations.

A 96 GeV Higgs boson in the general NMSSM

1 code implementation8 Jun 2019 Kiwoon Choi, Sang Hui Im, Kwang Sik Jeong, Chan Beom Park

We also show that the viable region of mixing parameter space is considerably modified if the higgsino mass parameter is around the weak scale, mainly because of the Higgs coupling to photons induced by the charged higgsinos.

$B$-meson anomalies and Higgs physics in flavored $U(1)'$ model

1 code implementation24 Nov 2017 Ligong Bian, Hyun Min Lee, Chan Beom Park

In this article, we focus on the phenomenology of the Higgs sector of the model including extra Higgs doublet and singlet scalars.

M_T2-assisted on-shell reconstruction of missing momenta and its application to spin measurement at the LHC

1 code implementation27 Oct 2008 Won Sang Cho, Kiwoon Choi, Yeong Gyun Kim, Chan Beom Park

We propose a scheme to assign a 4-momentum to each WIMP in new physics event producing a pair of mother particles each of which decays to an invisible weakly interacting massive particle (WIMP) plus some visible particle(s).
