弱尺度超對(duì)稱(chēng)

內(nèi)容概要

　　超對(duì)稱(chēng)是自然界中一種新的對(duì)稱(chēng)性。本書(shū)全面系統(tǒng)地介紹了粒子物理學(xué)中的超對(duì)稱(chēng)，首先闡述了超對(duì)稱(chēng)的基本概念，接著展示了如何將超對(duì)稱(chēng)納入到描述基本粒子的理論框架中。書(shū)中采用了高能物理實(shí)驗(yàn)學(xué)家和唯象學(xué)家們所熟悉的四分量旋量表示，從而使得本書(shū)的可讀性大為增強(qiáng)。本書(shū)迅速地將讀者從抽象描述帶入到構(gòu)造基本粒子的超對(duì)稱(chēng)性規(guī)范理論，并最終給出對(duì)撞機(jī)和宇宙學(xué)實(shí)驗(yàn)觀(guān)測(cè)量的計(jì)算。本書(shū)與高能實(shí)驗(yàn)和唯象理論結(jié)合得非常緊密，這是本書(shū)的一大特色。對(duì)于從事粒子物理實(shí)驗(yàn)和唯象研究的物理學(xué)家和研究生而言，這是一本全面、實(shí)用且易懂的教學(xué)參考書(shū)，并且包括大量的練習(xí)和補(bǔ)充材料，非常合適作為超對(duì)稱(chēng)理論的入門(mén)教材。閱讀本書(shū)需要一些基本的標(biāo)準(zhǔn)模型和量子場(chǎng)論知識(shí)。
　　讀者對(duì)象：粒子物理、理論物理和場(chǎng)論等專(zhuān)業(yè)的高年級(jí)本科生、研究生和相關(guān)專(zhuān)業(yè)的科研人員。

章節(jié)摘錄

版權(quán)頁(yè)：   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．
