Tevatron重味光谱

Heavy Flavor Spectroscopy at the Tevatron

Diego Tonelli

摘要:

在过去的十年中,CDF和在Tevatron的实验一直在追求一个广泛的重味光谱计划,提供了显着的进步,在理解质量的基态和轨道激发的b-强子,和奇异的XYZ状态的现象学。它也带来了我们对底重子知识的突破,首次观测到了Sigma_b ^{+-(*)}、Xi_b ^-和Omega_b ^-族。在简要回顾了以前的结果之后,我将集中讨论最新的CDF测量的Sigma_b ^{+-(*)}重子和奇异J/ψ态,都更新到6 fb ^{-1}的数据,并对粲重子进行新的分析

英文摘要:

During the last decade, the CDF and DØ experiments at the Tevatron have been pursuing an extensive heavy flavor spectroscopy program that provides significant advancements in the understanding of masses of ground state and orbitally excited b-hadrons, and phenomenology of exotic XYZ states. It also yields a breakthrough in our knowledge of bottom baryons with the first observation of the Sigma_b^{+-(*)}, Xi_b^-, and Omega_b^- families. After briefly reviewing previous results, I will focus on the latest CDF measurements of Sigma_b^{+-(*)} baryons and exotic J/psiphi states, both updated to 6 fb^{-1} of data, and on a new analysis of charmed baryons
