タイトル：The puzzle of angular momentum conservation in beta decay and related processes

要旨：We ask the question of how angular momentum is conserved in a number of related processes, from elastic scattering of a circularly polarized photon by an atom, where the scattered photon has a different spin direction than the original photon; to scattering of a fully relativistic spin-1/2 particle by a central potential; to inverse beta decay in which an electron is emitted following the capture of a neutrino on a nucleus, where the final spin is in a different direction than that of the neutrino – an apparent change of angular momentum.

  The seeming non-conservation of angular momentum arises, in fact, in the quantum measurement process in which the measuring apparatus does not have an initially well-defined angular momentum, but is localized in direction in the outside world.  We generalize the discussion to massive neutrinos and electrons, and examine nuclear beta decay and electron-positron annihilation processes through the same lens, enabling physical insights into angular and helicity distributions in these reactions.

Announcement of the 27th Kincha-kai:

Date: Friday, July 17, 2026, 16:30–18:00 (talk begins at 16:30)

Venue (Tsukuba): Main Research Building, 1F, Conference Room 1

Speaker:  Dr. Hiroshi Fukuyama (UTokyo CRC/KEK QUP)

Title: The Fascination of Ultra-Low-Energy Physics: Focusing on Quantum Condensed Matter Systems

Abstract:

The helium isotopes 4^{4}4He, a bosonic composite particle, and 3^{3}3He, a fermionic composite particle, possess the strongest quantum character among all atomic and molecular systems owing to their small atomic masses and weak interatomic interactions. When cooled below a few kelvin under various dimensionalities and pressures, they form a wide variety of quantum condensed phases, including quantum liquids, quantum solids, and quantum liquid crystals.

Upon further cooling to ultralow temperatures (down to ∼100\sim100∼100 mK for 4^{4}4He and ∼100\sim100∼100 μK for 3^{3}3He), these systems exhibit diverse low-temperature phases such as superfluidity, quantum spin liquids, and nuclear ferromagnetism. These phases are accompanied by characteristic elementary excitations—including phonons, rotons, quasiparticles, and Majorana quasiparticles—as well as topological defects such as quantized vortices and order-parameter textures. The associated phase transitions are equally rich, encompassing first-order, second-order, lambda-type, and Berezinskii–Kosterlitz–Thouless transitions.

Quantum fluids and solids also provide fertile ground for concepts shared with high-energy and astrophysics, including spontaneous symmetry breaking, the Kibble–Zurek mechanism, and Majorana particles. In this lecture, I will highlight several examples illustrating the fascination and broad scientific significance of the field known as Quantum Fluids and Solids (QFS) research.

タイトル：電子・イオン衝突で探る核子・原子核の内部構造 — 物質のグルーオン構造 —
(Probing Nucleons and Nuclei through Electron-Ion Collisions: The Gluonic Structure of Matter)
言語：英語

要旨：通常の物質の質量、スピン、そして三次元構造は何によって決まるのだろうか。クォークとグルーオンは核子や原子核を構成する基本自由度であるが、それらの集団的ダイナミクス、
とりわけグルーオンが支配的となる量子色力学（QCD）の領域については、未解明の問題が数多く残されている。

現在ブルックヘブン国立研究所で建設中の電子・イオン衝突型加速器（Electron-Ion Collider; EIC）は、電子と陽子・原子核の衝突を通じて、この領域を探究する新たな機会を提供する。
高エネルギー電子散乱をこれまでにない精度とルミノシティで行うことにより、EICでは核子や原子核の内部構造を多次元的に可視化するとともに、グルーオンが質量やスピンらには物質中の集団現象にどのような役割を果たしているのかを明らかにすることを目指す。

これらの物理目標の実現には、新世代の実験技術も不可欠である。ePIC実験では、高精度タイミング検出器、先進的なシリコン飛跡検出器、ストリーミング型データ収集、さらにAIやHPCを活用したデータ処理技術の開発が進められている。

本講演では、EICを推進する主要な物理課題について、特に核子・原子核の構造におけるグルーオンの役割に焦点を当てて概観するとともに、
これらの測定を可能にする実験技術および技術開発について紹介する。

28th Kincha-kai Announcement

Date & Time: Friday, September 18, 2026, 16:30–18:00 (The lecture starts at 16:30)
Location: Room 1, 1st Floor, Research Main Building, Tsukuba Campus
Remote Hubs: Tokai Campus (JRB 2nd Floor Conference Room), Wako Campus (Nishina Memorial Building Room 106)

Speaker: Dr. Taku Gunji (Graduate School of Science, The University of Tokyo)
Title: Probing Nucleons and Nuclei through Electron-Ion Collisions: The Gluonic Structure of Matter
Language: English

Abstract:
What determines the mass, spin, and three-dimensional structure of ordinary matter? Although quarks and gluons are the fundamental constituents of nucleons and nuclei, much of their collective dynamics remains to be understood, particularly in the gluon-dominated regime of Quantum Chromodynamics (QCD).

The Electron-Ion Collider (EIC), currently under construction at Brookhaven National Laboratory, will provide a unique opportunity to explore this regime by colliding electrons with protons and nuclei. By combining high-energy electron scattering with unprecedented precision and luminosity, the EIC will allow us to image the internal structure of nucleons and nuclei in new dimensions and to investigate how gluons generate mass, spin, and collective phenomena in matter.

Achieving these goals also requires a new generation of experimental technologies. The ePIC experiment is developing precision-timing detectors, advanced silicon tracking, streaming data acquisition, and AI- and HPC-based data processing to reconstruct and analyze collisions in real time.

In this Kincha-kai, I will discuss the physics questions driving the EIC, with a particular focus on the role of gluons in the structure of nucleons and nuclei, and introduce the experimental and technological advances that will make these measurements possible.
