Dark Matter "Collider" from Inelastic Boosted Dark Matter

Doojin Kim, Jong-Chul Park, Seodong Shin

We propose a novel dark matter (DM) detection strategy for the models with non-minimal dark sector. The main ingredients in the underlying DM scenario are a boosted DM particle and…

Prompt atmospheric neutrino flux from the various QCD models

Yu Seon Jeong, Atri Bhattacharya, Rikard Enberg +4

We evaluate the prompt atmospheric neutrino flux using the different QCD models for heavy quark production including the $b$ quark contribution. We include the nuclear correction a…

Delayed versus accelerated quarkonium formation in a magnetic field

Kei Suzuki, Su Houng Lee

Formation time of heavy quarkonia in a homogeneous magnetic field is analyzed by using a phenomenological ansatz of the vector current correlator. Because the existence of a magnet…

Probing new physics in $B \to D ℓ^{+} ℓ^{-}$ decays by using angular asymmetries

C. S. Kim, Dibyakrupa Sahoo

We present the fully general, model independent study of a few rare semileptonic $B$ decays that get dominant contributions from $W$ -annihilation and $W$ -exchange diagrams, in part…

Remarks on the Standard Model predictions for $R (D)$ and $R (D^{*})$

C. S. Kim, G. Lopez-Castro, S. L. Tostado +1

Semileptonic $b \to c$ transitions, and in particular the ratios $R (D^{(*)}) = \frac{Γ ( B \to D ^{(*)} τ ν )}{Γ ( B \to D ^{(*)} ℓ ν )}$ , can be used to test the univers…

Investigating the jet activity accompanying the production at the LHC of a massive scalar particle decaying into photons

Benjamin Fuks, Dong Woo Kang, Seong Chan Park +1

We study the jet activity that accompanies the production by gluon fusion of a new physics scalar particle decaying into photons at the LHC. In the considered scenarios, both the p…

New constraints and discovery potential for Higgs to Higgs cascade decays through vectorlike leptons

Radovan Dermisek, Enrico Lunghi, Seodong Shin

One of the cleanest signatures of a heavy Higgs boson in models with vectorlike leptons is $H \to e_{4}^{\pm} ℓ^{\mp} \to h ℓ^{+} ℓ^{-}$ which, in two Higgs doublet model type-II, can…

Prompt atmospheric neutrino fluxes: perturbative QCD models and nuclear effects

Atri Bhattacharya, Rikard Enberg, Yu Seon Jeong +4

We evaluate the prompt atmospheric neutrino flux at high energies using three different frameworks for calculating the heavy quark production cross section in QCD: NLO perturbative…

Distinguishing Dirac/Majorana Sterile Neutrinos at the LHC

Claudio O. Dib, C. S. Kim, Kechen Wang +1

We study the purely leptonic decays of $W^{\pm} \to e^{\pm} e^{\pm} μ^{\mp} ν$ and $μ^{\pm} μ^{\pm} e^{\mp} ν$ produced at the LHC, induced by sterile neutrinos with mass $m_{N}$ below $M_{W}$ in th…

Dibaryons with two strange quarks and one heavy flavor in a constituent quark model

Aaron Park, Woosung Park, Su Houng Lee

We investigate the symmetry property and the stability of dibaryons containing two strange quarks and one heavy flavor with $I = \frac{1}{2}$ . We construct the wave function of the d…

Negative-parity nucleon excited state in nuclear matter

Keisuke Ohtani, Philipp Gubler, Makoto Oka

Spectral functions of the nucleon and its negative parity excited state in nuclear matter are studied using QCD sum rules and the maximum entropy method (MEM). It is found that in-…

Rare decays of B mesons via on-shell sterile neutrinos

Gorazd Cvetic, C. S. Kim

In view of the projected high number of produced $B$ mesons in Belle II experiment ( $\sim 1 0^{10}$ per year), in addition to the presently ongoing LHC-b, we calculate the rate of d…

Constraints on $Z^{'}$ Boson within Minimal Flavor Violation

C. S. Kim, Xing-Bo Yuan, Ya-Juan Zheng

We explore a $Z^{'}$ boson coupled only with the Standard Model (SM) fermions ( $Z^{'} f f ˉ$ ) in the framework of Minimal Flavor Violation. We study its effects on the pro…
