在sqrt(s)= 7 ATLAS的pp碰撞中电子和光子的性质及电子p_T谱的测量

Electron and Photon Performance and Electron p_T Spectrum Measurement with ATLAS in pp Collisions at sqrt(s) = 7 TeV

Scott Snyder

摘要:

我们讨论的早期表现的重建的电子和光子在ATLAS的质心能量为7 TeV。我们使用一个约为15 nb^-1的数据样本,测量了包容电子的横向动量分布,观测到了瞬发光子,并测量了该样本的纯度。我们还用78 nb^-1的数据样本证明了J/psi介子的重构。

英文摘要:

We discuss the early performance of the reconstruction of electrons and photons at ATLAS with a center-of-mass energy of 7 TeV. Using a data sample of about 15 nb^-1, we present a measurement of the transverse momentum distribution of inclusive electrons, as well as an observation of prompt photons and a measurement of the purity of this sample. We also demonstrate the reconstruction of J/psi mesons with a data sample of 78 nb^-1.
