Higgs Inflation and the Refined dS Conjecture

Dhong Yeon Cheong, Sung Mook Lee, Seong Chan Park

The refined de Sitter derivative conjecture provides constraints to potentials that are low energy effective theories of quantum gravity. It can give direct bounds on inflationary…

On the violent preheating in the mixed Higgs- inflationary model

Minxi He, Ryusuke Jinno, Kohei Kamada +3

It has been argued that the mixed Higgs- model acts as the UV extension of the Higgs inflation, pushing up its cut-off scale in the vacuum close up to the Planck scale. In thi…

Angular distribution as an effective probe of new physics in semi-hadronic three-body meson decays

C. S. Kim, Seong Chan Park, Dibyakrupa Sahoo

We analyze, in a fully model-independent manner, the effects of new physics on a few semi-hadronic three-body meson decays of the type , where , are…

Where is the stable Pentaquark

Woosung Park, Sungtae Cho, Su Houng Lee

We systematically analyze the flavor color spin structure of the pentaquark system in a constituent quark model based on the chromomagnetic interaction in both the SU(…

Minimal gauge inflation and the refined Swampland conjecture

Seong Chan Park

The refined de Sitter (dS) conjecture provides two consistency conditions for an effective theory potential of a quantum gravity theory. Any inflationary model can be checked by th…

Probing New Intra-Atomic Force with Isotope Shifts: A Neat Thing to Do

Yasuhiro Yamamoto

We discuss a new method to search for a new very weakly interacting light boson with extremely precise atomic spectroscopy, namely, the atomic clock. The contribution of the new ph…

Collider probes of singlet fermionic dark matter scenarios for the Fermi gamma-ray excess

Yeong Gyun Kim, Chan Beom Park, Seodong Shin

We investigate the collider signatures of the three benchmark points in the singlet fermionic dark matter model. The benchmark points, which were introduced previously to explain t…

Constraints on a sub-eV scale sterile neutrino from non-oscillation measurements

C. S. Kim, G. López Castro, Dibyakrupa Sahoo

Anomalies in several short-baseline neutrino oscillation experiments suggest the possible existence of sterile neutrinos at about eV scale having appreciable mixing with the alread…

Transverse momentum broadening and collinear radiation at NLO in the SYM plasma

Jacopo Ghiglieri, HyungJoo Kim

We compute O(g) NLO corrections to the transverse scattering kernel and transverse momentum broadening coefficient of weakly-coupled SYM. Based on this, w…

Probing new physics with high-multiplicity events: UHE neutrinos at air-shower detector arrays

Yongsoo Jho, Seong Chan Park

Semi-classical processes such as production and decay of electroweak sphaleron in the Standard Model and also microscopic black hole in low scale gravity scenario typically involve…

Analysis of the meson decay in local tensor bilinear representation

Kie Sang Jeong, Su Houng Lee, Yongseok Oh

We explore the validity of vector meson dominance in the radiative decay of the meson. In order to explain the violation of the vector meson dominance hypothesis in thi…

Boosted Dark Matter Quarrying at Surface Neutrino Detectors

Doojin Kim, Kyoungchul Kong, Jong-Chul Park +1

We propose the idea of "Earth Shielding" to reject cosmic-ray backgrounds, in the search for boosted dark matter at surface neutrino detectors, resulting in the enhancement of the…

Search for Boosted Dark Matter at ProtoDUNE

Animesh Chatterjee, Albert De Roeck, Doojin Kim +5

We propose the first experimental test of the inelastic boosted dark matter hypothesis, capitalizing on the new physics potential with the imminent data taking of the ProtoDUNE det…

Search for sterile neutrinos decaying into pions at the LHC

Claudio O. Dib, C. S. Kim, Nicolas A. Neill +1

We study the possibility to observe sterile neutrinos with masses in the range between 5 GeV and 20 GeV at the LHC, using the exclusive semileptonic modes involving pions, namely W…

Tribaryon configurations and the inevitable three nucleon repulsions at short distance

Aaron Park, Woosung Park, Su Houng Lee

We decompose the tribaryon configuration in terms of SU(3) flavor and spin state and analyse their color-spin-flavor wave function following Pauli principle. By comparing the color…
