In content we would like to start tracking lab news for 2022. This should include information about all announcements and important things for the lab.

For example,

Each news item can be a new page under news created by the Hugo command,

hugo new content\news\<title.en.md> for English pages

hugo new content\news\<title.jp.md> for Japanese pages

Change the title to be the title of the announcement.

  4. the 4th Sohaken seminar

Speaker:　Wong, Yvonne (The University of New South Wales) Date:　Wednesday 10/26 from 13:30 JST Title:　Neutrinos in Cosmology: Calculations of the neutrino-to-photon ratio and the spatial neutrino density distribution Abstract:

Standard hot Big Bang cosmology predicts the existence of a cosmic neutrino background (CnuB), analogous to its better known cousin, the cosmic microwave background (CMB). With a predicted number density of about 100 neutrinos+antineutrinos per cubic centre per family today, the shear abundance of these CnuB neutrinos ensures that they have a nontrivial impact on the many stages of the evolution of the universe. An immediate corollary is that cosmological observations such as the CMB anisotropies and the large-scale matter distribution are sensitive to the CnuB, and can in turn be used to constrain its properties.

In this talk, I will report on a recent precision theoretical calculation of the neutrino-to-photon energy density ratio---commonly referred to as the "effective number of thermalised neutrino species" Neff---within the Standard Model of particle physics, as well as discuss some recent works in the computation of massive neutrino effects on the spatial distribution of matter and the clustering of the CnuB itself.

  1. The 5th seminar by Umeeda-san Speaker:　梅枝 宏之 (Academia Sinica) Date:　Friday 10/28 from 13:30 JST Title:　Right-handed current, B->Xu l nu decays and non-trivial topology in QCD vacuum Abstract: We study violation of quark-hadron duality for B->X_ulnu decays in the presence of the right-handed current (RHC). In this case, it is shown that the fermionic zero mode of an intermediate light quark, which is induced by an instanton, gives a non-vanishing contribution owing to its chirality structure. Within a certain approximation relying on the single instanton, the finite distance singularity, causing violation of quark-hadron duality, is extracted analytically. As a result, it is shown that duality violation for the lepton energy distribution in B->X_ulnu decays is possibly comparable to the chirally-suppressed perturbative contribution in the RHC, for a particular region in the phase space.

  2. 12th Journal club on November 2nd Speaker : Yusuke Shimizu Reference Title : The Exclusive Vision of Rare K and B Decays and of the Quark Mixing in the Standard Model By : Andrzej J. Buras and Elena Venturini DOI : https://link.springer.com/article/10.1140/epjc/s10052-022-10583-8

  3. 13th Journal Club on November 9th Speaker: Azumi Sakai Reference Title: Dilepton Spectroscopy of QCD Matter at Collider Energies By: Ralf Rapp DOI: 10.1155/2013/148253

  4. D1 and D2 中間発表 on November 11th by Hironori Takei and Masahiko Taniguchi

  5. The 6th seminar on November 11th Speaker:　Takayuki Miyagi (TU Darmstadt, Germany) Date:　Friday 11/11 from 15:00 JST Title:　Nuclear equation of state and 208Pb

Abstract:
The neutron skin thickness could be crucial to constrain the nuclear equation of state (EoS). According to the phenomenological mean-field type studies, the neutron skin of 208Pb is known to be strongly correlated with the neutron star pressure, motivating neutron skin thickness measurements. From this background, it is important to test the correlation through the nuclear first principle calculation. In this talk, I will show the results for 208Pb and nuclear EoS parameters from the first principle calculation.

  1. M1 中間発表 on November 25th by Taihei Kuroiwa, Reishi Maeta, Shoko Ono, Ryu Takagi, Shonosuke Takeshita, and Naoki Yoshioka.
