Heavy Color-Octet Particles at the LHC
Chien-Yi Chen, Ayres Freitas, Tao Han +1
Many new-physics models, especially those with a color-triplet top-quark partner, contain a heavy color-octet state. The "naturalness" argument for a light Higgs boson requires tha…
New Physics from the Top at the LHC
Chien-Yi Chen, Ayres Freitas, Tao Han +1
The top quark may hold the key to new physics associated with the electroweak symmetry-breaking sector, given its large mass and enhanced coupling to the Higgs sector. We systemati…
Nonperturbative m_X cut effects in B -> Xs l+ l- observables
Keith S. M. Lee, Frank J. Tackmann
Recently, it was shown that in inclusive B -> Xs l+ l- decay, an angular decomposition provides three independent (q^2 dependent) observables. A strategy was formulated to extract…
Trispectrum versus Bispectrum in Single-Field Inflation
Kevin T. Engel, Keith S. M. Lee, Mark B. Wise
In the standard slow-roll inflationary cosmology, quantum fluctuations in a single field, the inflaton, generate approximately Gaussian primordial density perturbations. At present…
Subleading Shape-Function Effects and the Extraction of |V_ub|
Keith S. M. Lee
We derive a class of formulae relating moments of B -> Xu l nu to B -> Xs gamma in the shape function region, where m_X^2 ~ m_b Lambda_QCD. We also derive an analogous class of for…
Extracting short distance information from b -> s l+ l- effectively
Keith S. M. Lee, Zoltan Ligeti, Iain W. Stewart +1
We point out that in inclusive B -> Xs l+ l- decay an angular decomposition provides a third (q^2 dependent) observable sensitive to a different combination of Wilson coefficients…
