Primordial Black Holes in Higgs- Inflation as a Whole Dark Matter

Dhong Yeon Cheong, Sung Mook Lee, Seong Chan Park

Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included term. We show that for parameters consistent with Standard Model measure…

Intrinsic three-body nuclear interaction from a constituent quark model

Aaron Park, Su Houng Lee

We study the short distance part of the intrinsic three-nucleon interaction in a constituent quark model with color-spin interaction. For that purpose we first calculate the transf…

Baryon-baryon interactions at short distances -- constituent quark model meets lattice QCD

Aaron Park, Su Houng Lee, Takashi Inoue +1

The interaction energies between two baryons at short distance in different flavor channels are calculated from the constituent quark model (CQM) and are compared with the recent l…

White Paper on New Opportunities at the Next-Generation Neutrino Experiments (Part 1: BSM Neutrino Physics and Dark Matter)

C. A. Argüelles, A. J. Aurisano, B. Batell +47

With the advent of a new generation of neutrino experiments which leverage high-intensity neutrino beams for precision measurements, it is timely to explore physics topics beyond t…

Cascade decays of Heavy Higgs bosons through vectorlike quarks

Radovan Dermisek, Enrico Lunghi, Seodong Shin

We study cascade decays of heavy neutral Higgs bosons through vectorlike quarks. We focus on scenarios where decay modes into pairs of vectorlike quarks are not kinematically open…

Dark matter signals from timing spectra at neutrino experiments

Bhaskar Dutta, Doojin Kim, Shu Liao +3

We propose a novel strategy to search for new physics in timing spectra, envisioning the situation in which a new particle comes from the decay of its heavier partner with a finite…

Explaining the ANITA Anomaly with Inelastic Boosted Dark Matter

Lucien Heurtier, Doojin Kim, Jong-Chul Park +1

We propose a new physics scenario in which the decay of a very heavy dark-matter candidate which does not interact with the neutrino sector could explain the two anomalous events r…

Search for muon-philic new light gauge boson at Belle II

Yongsoo Jho, Youngjoon Kwon, Seong Chan Park +1

Motivated by the long-lasting discrepancy in the anomalous magnetic moment of muon, we consider a new muon-specific force mediated by a light gauge boson, , with mass $m_…

Sensitivity bounds on heavy neutrino mixing and from LHCb upgrade

Gorazd Cvetic, C. S. Kim

Decays of heavy pseudoscalar mesons , , and at LHCb upgrade are considered, which produce either two equal sign muons or taus. In addition, we consider the anal…

Higgs inflation in metric and Palatini formalisms: Required suppression of higher dimensional operators

Ryusuke Jinno, Mio Kubota, Kin-ya Oda +1

We investigate the sensitivity of Higgs(-like) inflation to higher dimensional operators in the nonminimal couplings and in the potential, both in the metric and Palatini formalism…

Search for light sterile neutrinos from decays at the LHC

Claudio O. Dib, Choong Sun Kim, Sebastian Tapia Araya

We study the feasibility to observe sterile neutrinos with masses in the range 5 GeV GeV at the LHC, using exclusive semileptonic modes involving pions, $W\to \ell N \…

Charmonium Excitation functions in A Collisions

Gy. Wolf, G. Balassa, P. Kovacs +2

We study the excitation function of the low-lying charmonium state: (3686) in Au collisions taking into account their in-medium propagation. The time evolution of the s…

Hunting for Vectorlike Quarks

Radovan Dermisek, Enrico Lunghi, Seodong Shin

We analyze decays of vectorlike quarks in extensions of the standard model and a two Higgs doublet model. We identify several typical patterns of branching ratios of the lightest n…
