37. Neutrino self-interaction and MSW effects on the supernova neutrino-process

Heamin Ko (Soongsil University)

Short Contribution

We study the nuclear abundances produced by neutrino process during supernova (SN) explosion. In this presentation, we show the elements of $^{7}$Li, $^{11}$B, $^{92}$Nb, $^{98}$Tc, and $^{138}$La, which are mainly produced by neutrino reactions. To describe the neutrino-induced reaction rates, we consider the neutrino scattering with electron background and neutrinos themselves near the...

36. The electron screening effect with a magnetic field on the massive star

EunSeok Hwang (Soongsil University)

Short Contribution

We investigate the electron screening effect on the stellar nucleosynthesis. The dense electron gases in the stellar environments screen the Coulomb interaction between reacting nuclei. In particular, the role of screening effects becomes important in the massive star since it consists of dense ions. In addition, most stellar objects have a magnetic field, which affects the electric screening...

47. Lepton Flavour Violation (LFV) searches at Belle II: tau->3mu analysis expectations

Mr Alberto Martini (INFN-Roma3)

24/01/2020, 17:40

Short Contribution

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory.
Exploiting the improved collider, Belle II will play an important role in the Lepton Flavour Violation (LFV) field by collecting a huge amount of statistics (50 ab$^{-1}$ expected by 2028) which allows to probe new physics scenario...

28. Production of leptons from charm and beauty quarks with ALICE at the LHC

Sudhir Pandurang Rode (IIT Indore)

24/01/2020, 18:00

Short Contribution

Due to their large masses, heavy quarks are produced in the
early stages of the relativistic heavy-ion collisions via initial hard
scatterings. Therefore, they are considered as effective probes of the
hot and dense QCD medium formed in such collisions since they
witness its full evolution. In pp collisions, the measurement of heavy-
flavour hadron production cross-sections can be used to test...

35. Lifetime measurements in the deformed nuclei $^{178}$W and $^{178,182}$Os

Matthias Rudigier (IKP, TU Darmstadt, Germany)

Extended Contribution

New data on lifetimes of excited states in the ground state band of $^{178}$W,
$^{178}$Os, and $^{182}$Os are presented. The mean lifetimes of the 2$^+_1$ and 4$^+_1$
were measured using the
fast timing method with LaBr$_3$ detectors in the $\nu$-Ball setup at the IPN Orsay
and at HORUS at the IKP Cologne. The isotopes of interest were produced in fusion-evaporation
reactions. The new results...
