Determination of the strong coupling constant from the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV

D0 Collaboration, V. M. Abazov

We determine the strong coupling constant alphas and its energy dependence from the pT dependence of the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV. The st…

Search for New Physics with a Dijet plus Missing Transverse Energy Signature in p-pbar Collisions at sqrt(s) = 1.96 TeV

T. Aaltonen

We present results of a signature-based search for new physics using a dijet plus missing transverse energy data sample collected in 2 fb-1 of p-pbar collisions at sqrt(s) = 1.96 T…

Radiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter

The CMS Electromagnetic Calorimeter Group, P. Adzic, N. Almeida +267

Ensuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The produ…

A study of the associated production of photons and b-quark jets in p-pbar collisions at sqrt{s} = 1.96 TeV

CDF collaboration

The cross section for photon production in association with at least one jet containing a -quark hadron has been measured in proton antiproton collisions at TeV.…

Quantum Wall Crossing in N=2 Gauge Theories

Tudor Dimofte, Sergei Gukov, Yan Soibelman

We study refined and motivic wall-crossing formulas in N=2 supersymmetric gauge theories with SU(2) gauge group and N_f < 4 matter hypermultiplets in the fundamental representation…

Search for Fermion-Pair Decays $Q\Qbar \to (\t\Wmp)(\tbar\Wpm)$ in Same-Charge Dilepton Events

The CDF Collaboration

We report the most restrictive direct limits on masses of fourth-generation down-type quarks , and quark-like composite fermions ( or ), decaying promptly t…
