商品描述

This book offers construction of a renormalizable effective theory of electroweak-interacting spin-1 dark matter (DM). The effective theory realizes minimal but essential features of DM predicted in extra-dimension models, and enables to systematically treat non-perturbative corrections such as the Sommerfeld effects. Deriving an annihilation cross section including the Sommerfeld effects based on the effective theory, the author discusses the future sensitivity of observations to gamma-ray from the Galactic Center. As a result, the author explains the monochromatic gamma-ray signatures originate from two photons (γγ) or photon and Z boson (γZ) produced in the process of DM annihilations, and concludes a possible scenario that unstable neutral spin-1 particles (Z') appear and results in a spectral peak in addition to the one caused by γγ and γZ channels in gamma-ray observations. If those two spectral peaks are observed, the masses of spin-1 DM and Z' would be reconstructed.

商品描述(中文翻譯)

本書提供了一個可重整的有效理論，用於描述與電弱相互作用的自旋-1暗物質（DM）。該有效理論實現了額外維度模型中預測的DM的最小但必要特徵，並能夠系統地處理非微擾修正，如Sommerfeld效應。作者基於該有效理論推導了包括Sommerfeld效應的湮滅截面，並討論了對銀河中心伽馬射線觀測的未來敏感性。結果，作者解釋了來自DM湮滅過程中產生的兩個光子（γγ）或光子和Z玻色子（γZ）的單色伽馬射線特徵，並得出一個可能的情景，即不穩定的中性自旋-1粒子（Z'）出現，並在伽馬射線觀測中產生一個光譜峰值，除了由γγ和γZ通道引起的峰值之外。如果觀察到這兩個光譜峰值，則可以重建自旋-1 DM和Z'的質量。

作者簡介

Motoko Fujiwara is a postdoc researcher at the Technical University of Munich. She received her Bachelor of Science from Keio University in 2014, her Master of Science from Nagoya University in 2017, and her Ph.D. of Science from Nagoya University in 2022 completing the work on electroweak-interacting dark matter. She worked as a postdoc researcher at the University of Tokyo and moved to the current position. Impressed by the fact that microscopic theories of elementary particles dominates macroscopic-scale systems such as the Universe, she focuses on particle physics and particle phenomenology.

Besides scientific research, she is also engaging in science communications. Motivated to promote reality of science and scientists, she organized a voluntary group of students who are interested in science communication and outreach activities, and released online articles to introduce mysteries in the Universe such as dark matter and the matter-antimatter asymmetry. These outreach activities were awarded as Nagoya University President's Award in March 2022.


作者簡介(中文翻譯)

藤原元子是慕尼黑工業大學的博士後研究員。她於2014年獲得慶應義塾大學的理學學士學位，2017年獲得名古屋大學的理學碩士學位，並於2022年獲得名古屋大學的理學博士學位，完成了有關電弱相互作用暗物質的研究工作。她曾在東京大學擔任博士後研究員，並轉至目前的職位。受到微觀粒子理論主導宇宙等宏觀尺度系統的事實所感動，她專注於粒子物理學和粒子現象學。

除了科學研究，她還積極參與科學傳播工作。為了推廣科學和科學家的真實性，她組織了一個由對科學傳播和外展活動感興趣的學生組成的志願團體，並發布了在線文章，介紹宇宙中的謎團，如暗物質和物質-反物質不對稱性。這些外展活動於2022年3月獲得了名古屋大學校長獎。
