內(nèi)容概要
超對稱是自然界中一種新的對稱性。本書全面系統(tǒng)地介紹了粒子物理學中的超對稱,首先闡述了超對稱的基本概念,接著展示了如何將超對稱納入到描述基本粒子的理論框架中。書中采用了高能物理實驗學家和唯象學家們所熟悉的四分量旋量表示,從而使得本書的可讀性大為增強。本書迅速地將讀者從抽象描述帶入到構(gòu)造基本粒子的超對稱性規(guī)范理論,并最終給出對撞機和宇宙學實驗觀測量的計算。本書與高能實驗和唯象理論結(jié)合得非常緊密,這是本書的一大特色。對于從事粒子物理實驗和唯象研究的物理學家和研究生而言,這是一本全面、實用且易懂的教學參考書,并且包括大量的練習和補充材料,非常合適作為超對稱理論的入門教材。閱讀本書需要一些基本的標準模型和量子場論知識。
讀者對象:粒子物理、理論物理和場論等專業(yè)的高年級本科生、研究生和相關(guān)專業(yè)的科研人員。

章節(jié)摘錄
版權(quán)頁: 插圖: At the one—loop level,however,a coupling of (H)u to down—type fermions is induced.This induced coupling leads to a new contribution,proportional to vu,tothe down—type fermion mass matrix.Although this contribution is suppressed bya loop factor relative to the tree—level contribution,this suppression is (partially)compensated if tan β is sufficiently large.As a result, down—type Yukawa interactions and down—type quark mass matrices are no longer diagonalized by the sametransformation,and flavor—violating couplings of neutral Higgs scalars h,H,and Aemerge.In the limit of large mA,the Higgs sector becomes equivalent to the Stan—dard Model (SM) Higgs sector with a light Higgs boson h () HSM,and the effectsof flavor violation decouple from the low energy theory.The interesting featureis that the flavor—violating couplings of h,H, and A do not decouple for largesuperparticle mass parameters:being dimensionless,these couplings depend onlyon ratios of these mass parameters,and so remain finite even for very large valuesof SUSY mass parameters.
