Spin-1 quarkonia in a rotating frame and their spin contents

HyungJoo Kim, Sungtae Cho, Su Houng Lee

We propose a new way of studying the spin content of a hadron by looking at its response in a rotating frame. By collecting all responses of quarks and gluons in a rotating frame,…

DeeLeMa: Missing information search with Deep Learning for Mass estimation

Kayoung Ban, Dong Woo Kang, Tae-Geun Kim +2

We introduce DeeLeMa, a deep learning-based network for the analysis of energy and momentum in high-energy particle collisions. This novel approach is specifically designed to addr…

Primordial Black Holes as a Factory of Axions: Extragalactic Photons from Axions

Yongsoo Jho, Tae-Geun Kim, Jong-Chul Park +2

Primordial black holes (PBHs) are significant sources of axions and axion-like particles (ALPs), provided their Hawking temperature exceeds the particles' masses. Given the predomi…

On the mass spectrum of heavy Higgs bosons in two-Higgs-doublet model in the light of the CDF -mass anomaly

Dong-Won Jung, Yongtae Heo, Jae Sik Lee

We analyze the mass spectrum of the charged and neutral Higgs bosons in the framework of two Higgs doublet model (2HDM) in the light of the precision measurement of the boson m…

Disentangling longitudinal and transverse modes of the meson through dilepton and kaon decays

In Woo Park, Hiroyuki Sako, Kazuya Aoki +2

Angular distributions of meson decay amplitudes of and channels are computed using both specific interaction Lagrangians and simple arguments relying on angul…

Probing the non-standard neutrino interactions using quantum statistics

C. S. Kim, Janusz Rosiek, Dibyakrupa Sahoo

Using the well established principles of Lorentz invariance, CP and CPT symmetry, and quantum statistics we do a model-independent study of effects of possible non-standard couplin…

and : structures and productions in heavy ion collisions

Hyeongock Yun, Daeho Park, Sungsik Noh +7

We argue why the recently observed could either be a compact multiquark configuration or a loosely bound molecular configuration composed of charmed mesons, whereas the $X…

Search Prospects for Axion-like Particles at Rare Nuclear Isotope Accelerator Facilities

Wooyoung Jang, Doojin Kim, Kyoungchul Kong +7

We propose a novel experimental scheme, called DAMSA (Dump-produced Aboriginal Matter Searches at an Accelerator), for searching for dark-sector particles, using rare nuclear isoto…

Phenomenological implications on a hidden sector from the Festina Lente bound

Kayoung Ban, Dhong Yeon Cheong, Hiroshi Okada +3

We apply the Festina Lente (FL) bound on a hidden sector with gauge symmetries. Since the FL bound puts a lower bound on masses of particles charged under the gauge s…

The Inflaton that Could : Primordial Black Holes and Second Order Gravitational Waves from Tachyonic Instability induced in Higgs- Inflation

Dhong Yeon Cheong, Kazunori Kohri, Seong Chan Park

The running of the Higgs self coupling may lead to numerous phenomena in early universe cosmology. In this paper we introduce a scenario where the Higgs running induces turns in th…

meson properties in nuclear matter from QCD sum rules with chirally separated four-quark condensates

Jisu Kim, Philipp Gubler, Su Houng Lee

The modification of the meson spectrum in nuclear matter is studied in an updated QCD sum rule analysis, taking into account recent improvements in properly treating the chiral…

Transport coefficients of heavy quarkonia comparing with heavy quark coefficients

Juhee Hong, Su Houng Lee

We revisit the transport coefficients of heavy quarkonia moving in high-temperature QCD plasmas. The thermal width and mass shift for heavy quarkonia are closely related to the mom…

Impact of the CDF -mass anomaly on two Higgs doublet model

Yongtae Heo, Dong-Won Jung, Jae Sik Lee

We consider the implication of the recent CDF -mass anomaly in the general framework of two Higgs doublet model. We find that the large deviation of the and parameters f…

Lepton-flavor violating axions at MEG II

Yongsoo Jho, Simon Knapen, Diego Redigolo

We study the sensitivity of the existing MEG data to lepton flavor violating axion-like particles produced through and estimate the discovery potential for the up…

Production of (4312) state in electron-proton collisions

In Woo Park, Su Houng Lee, Sungtae Cho +1

We study the cross sections for the electro-production of particle, a recently discovered pentaquark state, in electron-proton collisions assuming possible quantum numb…
