Indirect Measurement of the Higgs Boson Width and Searches for Additional Higgs Bosons & Measurement of low pTD+ meson production cross section at CDF

利用在大型强子对撞机的ATLAS探测器收集的数据，从离壳产生和衰变到Z玻色子对的希格斯玻色子宽度的间接测量，其中一个Z玻色子衰变为轻子对，另一个衰变为中微子对。同样的最终状态也将被用来寻找新的高质量希格斯玻色子，这些粒子物理学标准模型的许多扩展都预测了希格斯玻色子，利用Tevatron对撞机CDF实验的数据集，测量了1.96TeV中心能量下质子-反质子碰撞中D ~+介子的产生截面。将进行大规模的能源。测量探测了一个尚未探索的低横向动量范围，低至1.5 GeV/c，使用的事件选择的标准，偏见最低限度的碰撞的功能。对于初始状态和碰撞能量，这仍然是一个独特的测量量，是重要的QCD研究和调整蒙特卡罗模拟。"

Using data collected with the ATLAS detector at the LHC an indirect measurement of the Higgs boson width from off-shell production and decay to Z-boson pairs where one Z boson decays to a lepton pair and the other to a neutrino pair will be performed. The same final state will also be used to search for new high mass Higgs bosons predicted in many extensions of the Standard Model of particle physics, and for Higgs bosons decays to dark matter particles.Using the full data set collected by the CDF experiment at the Tevatron collider in Run II a measurement of the D+ meson production cross-section in proton-antiproton collisions at 1.96 TeV center-of-mass energy will be performed. The measurement probes a yet unexplored low transverse-momentum range, down to 1.5 GeV/c, using events selected with criteria that bias minimally the features of the collision. For initial state and collision energy, this remains a unique measurement of quantities that are important for QCD studies and for tuning Monte Carlo simulations."
