Ultralight cold dark matter, also known as fuzzy dark matter or ultralight axion, is a scalar field with an extremely light mass of approximately 10^{-22} eV. In this model, dark matter in galactic halos exists in a Bose-Einstein condensate state and is described by a macroscopic wave function with a de Broglie wavelength on the order of a kiloparsec. This approach offers potential solutions...

11/29/24, 3:00 PM

2-3

The gravitational anomalies observed in galaxies and galaxy clusters based on standard gravity have been interpreted as the presence of dark matter. Internal orbital motions of nearby wide binaries (widely separated, long-period, gravitationally bound binary stars) are free from the effects of the inferred dark matter density in the Milky Way and thus can be used to directly probe...

31. Background Study for the GE1/1 Detector in the CMS Experiment

우현 허 (서울시립대학교 물리학과)

Poster

Poster

As a part of the CMS muon system upgrade, the installation of the GE1/1 detectors has been completed in 2020. Because the GE 1/1 system is located in the forward region of the CMS endcap, we expect high background rates due to the heavy radiation environment. There are some additional components of the electronics-induced noise which can affect the background rate measurement. So, they must be...

23. Deep Learning Application to the Analysis of Rare Top Decay t→sW at the LHC

지원 허 (서울시립대학교)

Poster

Poster

The Cabibbo-Kobayashi-Maskawa (CKM) matrix describes the flavor-changing interactions of quarks. The matrix element |Vts| describes the coupling between the top and strange quark, but the decay of t→sW is not directly seen yet. A direct measurement of |Vts| can be performed by identifying the strange jets from top decays. However, the extremely low ratio of t→sW compared to the dominant t→bW,...

현모 구 (서울시립대학교)

Poster

Poster

Considering the self-interaction of bosonic scalar Ultra-Light Dark Matter (ULDM) relaxes the constraints on its particle mass, typically estimated to be around ~1e−22 eV. We calculate the dynamical friction (DF) coefficient for a steady-state circular orbit induced by the gravitational wake of ULDM using multipole expansion. In the strong self-coupling regime, the leading-order term for the...

Poster

The ME0 detector, based on Gas Electron Multiplier (GEM) technology, is a forthcoming component of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider, designed to extend muon detection into the very-forward pseudorapidity region of 2.0 < |η| < 2.8. This region faces significant challenges due to high pileup rates, which complicate accurate muon reconstruction. This study...

동근 탁 (서울대학교)

Poster

Poster

Gamma-ray bursts (GRBs) are the most energetic explosions in the universe, and their afterglow emission provides an opportunity to probe the physics of relativistic shock waves in an extreme environment. Several key pieces for completing the picture of the GRB afterglow physics are still missing, including jet properties, emission mechanism, and particle acceleration. Here we present a study...

Poster

This study aims to develop and investigate the characteristics of a liquid scintillator solution using perovskite quantum dot structures. To date, there have been no specific examples of utilizing perovskite structures for particle detectors in high-energy or nuclear physics, making this research an exploration of a novel next-generation liquid scintillator solution. Currently, the synthesis...

24. Study for measuring |Vts| directly in dileptonic final state of top pair production at 13 TeV with the CMS detector

Dr 우진 장 (서울시립대학교)

Poster

Poster

Charged current weak interactions between quarks are governed by the CKM matrix. The matrix element Vts​ represents the coupling strength between top and strange quarks. The square of this element corresponds to the branching ratio of a top quark decaying into a strange quark and a W boson. This value can be inferred indirectly through measurements from B meson oscillations or obtained via a...

The experiment is set to begin...

33. Transformer-based Deep Regression Model for Estimating Missing Transverse Momentum

승진 양 (경희대학교)

Poster

We introduce a Transformer-based regression model for estimating missing transverse momentum (MET) at hadron colliders. MET represents an imbalance in the vector sum of transverse momenta for all reconstructed particles and serves as a proxy for invisible particles such as neutrinos and dark matter candidates. The deep learning model takes all reconstructed particles as input and directly...
