26. Highlights of recent Belle physics results
Prof. Youngjoon Kwon (Yonsei University)
04/06/2015, 14:00
In this talk, we present recent highlights of the physics results from the Belle experiment. This includes the new measurements on B --> D(*) τ ν decays which can have significant implications for physics beyond the Standard Model such as 2HDM(II). In addition, we will discuss new results on dark sector search from Belle and other related results.
29. Tau neutrino physics in SHiP
Dr Yuseon Jeong (Yonsei Univ.)
04/06/2015, 15:00
A new fixed target experiment at CERN, SHiP is planned to search for the hidden particles using charmed mesons produced with 400 GeV proton beam. This experiment is also ideal for the study of tau neutrinos. I will present the cross section and the fluxes of the tau neutrinos and antineutrinos from the decay of the charmed meson, D_s. Also, I will discuss the estimation of the detectable...
39. Weak nonleptonic decays of Ωc^0 baryon to axial-vector meson
Dr Rohit Dhir (Yonsei Univ.)
04/06/2015, 15:30
The axial-vector-emitting weak hadronic decays of the Ωc^0 baryon are investigated. After employing the factorization and the pole model framework to predict their branching ratios, we derive the symmetry- breaking effects on axial-vector-meson-baryon couplings and effects of flavor dependence on baryon- baryon weak transition amplitudes and, consequently, on their branching ratios.
46. The 3-3-1 Models and Implication to Astroparticle Physics
Ms Nguyen Thi Thuy (Yonsei Univ.)
04/06/2015, 16:20
We study two versions of 3-3-1 model. The minimal 3-3-1 model behaved as the simple 3-3-1 model with the replication of \eta or of \chi can provide realistic dark matter candidates. The relic density is figured out as a function of the dark matter mass by using micrOMEGAs package. In addition, the 3-3-1 model with neutral fermions can be extended into 3-3-1-1 model by considering the lepton...

28. Nonleptonic B Meson Decay in the Perturbative QCD approach
Dr Freddy Simanjuntak (Yonsei Univ.)
04/06/2015, 17:20
Using perturbative QCD approach, charmless $B_{u,d,s}\to VT$ decays are predicted. Their branching ratios, polarization fractions and direct CP violations are calculated. Within this approach the polarization fractions and the branching ratios of $B\to \phi(K_2^{*-}, \bar K_2^{*0})$ agree with the observed experimental data. However, the branching ratios of $B\to \omega(K_2^{*-}, \bar...

Dr Jae Ho Heo (Yonsei Univ.)
05/06/2015, 16:45
A triplet dark matter candidate from the thermal leptogenesis is considered with building a model. The model is based on the standard two Higgs doublet model and seesaw mechanism with Higgs triplets. The parameters (couplings and masses) are adjusted for the observed small neutrino mass and the leptogenesis. Dark matter particles can annihilate and decay in this model. The time evolution of...

43. Diquark Sum Rules for Exotic Baryons
Mr Sungsik Noh (Yonsei University)
Poster
We want to calculate the masses of Lambda*(1405) and N*(1535) through the diquark sum rules with the interpolating field proposed by the diquark cluster picture for the penta-quark components in baryons. According to the paper, International Journal of Modern Physics A Vol. 21, No. 27 (2006), B. S. Zou, the penta-quark components could be dominant for some excited baryons and the diquark...

Chan Young Lee (Yonsei University)
Talk
RAON is the heavy ion accelerator of the Rare Isotope Science Project (RISP), which is carried by Institute for Basic Science (IBS) in Korea. As its name shows, RISP has the plan to produce rare isotopes and RAON is their key item of the plan. Geant4 is the toolkit for the simulation of the passage of particles through matter. Using Geant4, plenty types of experiments could be run with the...
37. Nuclear symmetry energy in QCD phase
Mr Kie Sang Jeong (Yonsei Univ.)
Talk
In dense quark phase, one can imagine two situation. Normal quark pahse and color superconducting phase. For the normal phase, the quark matter symmetry energy can be obtained from hard dense loop(HDL) resummed grand potential. It reduces symmetry energy. In superconducting phase, symmetry energy becomes almost 3 times of one for the normal matter as liberal degree of freedom reduces to 1/3 of...
41. QCD sum rules for sigma hyperons in nuclear matter
Mr Giju Gue (Hardron physics)
Poster
Reproducing the paper(Jin, Xue-Min et al. Phys.Rev. C51 (1995) 347), We calculate the wilson coefficients of operator product expansion(OPE). Through this calculation, we will Study outline of the method, dispersion relation, operator product expansion(OPE), Borel transform, and propagator.
42. Rare Isotope Science Project
Mr Minhyuk Chung (Yonsei University)
Talk
There are many atoms from Hydrogen to Livermorium(116). But in the nature, the largest atom is Uranium(92). From Neptunium(93), large and heavy atoms should be made artificial, combining two atoms, and going larger and heavier, the atom cannot stand longer and easily broken(fission). This is same as neutron, in isotopes. When the number of neutron is much less or more than proton in a atom,...
38. Renormalization of dimension 6 gluon operators
Mr HyungJoo Kim (Yonsei Univ.)
Talk
We identify the independent dimension 6 twist 4 gluon operators and calculate their renormalization in the pure gauge theory. By constructing the renormalization group invariant combinations, we find the scale invariant condensates that can be estimated in nonperturbative calculations and used in QCD sum rules for heavy quark systems in medium.
51. Search for massive invisible particle X^0 in B^+ \to e^+ X^0 and B^+ \to \mu^+ X^0 decays
Mr Chan Seok Park (Yonsei Univ.)
Talk
We present a search for a non-Standard-Model particle X^0 in the mass range 0.1-1.8 GeV/c in B^+ \to e^+ X^0 and B^+ \to \mu^+ X^0 decays. The results are obtained from a 711 fb^{-1} data sample collected at the Y(4S) resonance, with the Belle detector at the KEKB energy asymmetric e^+ e^- collider. One B meson is fully reconstructed in a hadronic mode to enable the precise analysis of the...
48. Searching dark sector in rare B deacy
Mr Seokhee PARK (Yonsei Univ.)
Poster
Find dark sector in Υ(4S) resonance. 𝐵⁰ decays into two vector particles, and the vector particles decay into lepton pair, electron and muon pair. The vector particle has mass < 2.6GeV, half of 𝐵⁰. This is signal MC and generic MC study.
45. Standard model and concepts of supersymmetry
Mr KyeongHyeon Min (Yonsei Univ.)
Talk
Standard model is almost complete. In last 2013, we found higgs boson and we can explain many physical pheonomena to use standard model. But the standard model was not perfect because there are so many things that we cannot explain. For example, those are about dark matter, dark energy, gravity etc. Therefore we need some more comprehensive models and the theory of supersymmetry is the most...
50. Study of B0 --> l+ tau- using untagged method at Belle
Ms YoungSoo Sohn (Yonsei University)
Poster
The lepton-flavor-violating B decays B0 --> l+ tau- ( l = e, mu ) are forbidden in the Standard Model(SM) in the absence of nonzero neutrino masses, but can occur via one-loop diagrams if neutrino oscillations are included. In this presentation, suppression of background using Neural Network and signal sensitivity and expected upper limit will be presented. In addition, systematic uncertainty...
52. The Conceptual Introduction to Black Holes
Mr MoonJeong Kang (Yonsei Univ.)
Poster
The talk is about the very familiar, but only a little known astronomical object, the black holes. They could be mostly described classically by Schwarzschild metric, from which almost every property of them would be derived. We focus on the introduction to concepts, especially about the observable phenomena. We can identify black holes in two different kinds by whether rotating one or not....
30. Variational Method for X(3872)
Mr Aaron Park (Yonsei University)
Talk
Using the variational method, we calculate the mass of heavy tetraquark states in a nonrelativistic potential model with color confinement and spin hyperfine interaction. We investigate the stability of tetraquark states containing a heavy quark and an antiquark. We find that the lowest energy states just corresponds to the sum of the hadronic final states to which the X(3872) can decay.
