We investigate the uncertainties of the heavy-quark parton distribution functions in the variable flavor number scheme. Because the charm- and bottom-quark parton distribution func…
A supersymmetric solution to the bottom-quark cross section anomaly

Fully differential QCD corrections to single top quark final states
B. W. Harris, E. Laenen, L. Phaf +2
A new next-to-leading order Monte Carlo program for calculation of fully differential single top quark final states is described and first results presented. Both the s- and t-chan…
Higgs-Boson Production in Association with Bottom Quarks at Next-to-Leading Order
D. Dicus, T. Stelzer, Z. Sullivan +1
We argue that the leading-order subprocess for Higgs-boson production in association with bottom quarks is (b\bar{b} -> H). This process is an important source of Higgs bosons with…

T. Stelzer, Z. Sullivan, S. Willenbrock
Single-top-quark production via W-gluon fusion at hadron colliders provides an opportunity to directly probe the charged-current interaction of the top quark. We calculate the next…
Tevatron-for-LHC Report: Top and Electroweak Physics
C. E. Gerber, P. Murat, T. M. P. Tait +59
The top quark and electroweak bosons (W and Z) represent the most massive fundamental particles yet discovered, and as such refer directly to the Standard Model's greatest remainin…
Single-top-quark production at hadron colliders
T. Stelzer, Z. Sullivan, S. Willenbrock
Single-top-quark production probes the charged-current weak interaction of the top quark, and provides a direct measurement of the CKM matrix element V_{tb}. We perform two indepen…
The fully differential single-top-quark cross section in next-to-leading order QCD

We present a new next-to-leading order calculation for fully differential single-top-quark final states. The calculation is performed using phase space slicing and dipole subtracti…

This is the "TeV4LHC" report of the "Physics Landscapes" Working Group, focused on facilitating the start-up of physics explorations at the LHC by using the experience gained at th…
Toward High Precision Higgs-Boson Measurements at the International Linear e+e- Collider
S. Heinemeyer, S. Kanemura, H. Logan +31
This report reviews the properties of Higgs bosons in the Standard Model (SM) and its various extensions. We give an extensive overview about the potential of the ILC operated at c…
Low-Energy Supersymmetry and the Tevatron Bottom-Quark Cross Section
E. L. Berger, B. W. Harris, D. E. Kaplan +3
A long-standing discrepancy between the bottom-quark production cross section and predictions of perturbative quantum chromodynamics is addressed. We show that pair production of l…
