Perturbative SO(10) GUT and the Minimal Higgs Sector
Soren Wiesenfeldt, Scott Willenbrock
The breaking of SO(10) to SU(3)_C x U(1)_EM can be accomplished by just four Higgs fields: the symmetric rank-two tensor, S(54); a pair of spinors, C(16) and Cbar(16bar); and a vec…
Choosing the Factorization Scale in Perturbative QCD
Fabio Maltoni, Thomas McElmurry, Robert Putman +1
We define the collinear factorization scheme, which absorbs only the collinear physics into the parton distribution functions. In order to isolate the collinear physics, we introdu…
Sterile Neutrinos and Global Symmetries
J. Sayre, S. Wiesenfeldt, S. Willenbrock
We use an effective-field-theory approach to construct models with naturally light sterile neutrinos, due to either exact or accidental global symmetries. The most attractive model…
Symmetries of the Standard Model
Scott Willenbrock
I present an overview of the standard model, concentrating on its global continuous symmetries, both exact and approximate. There are four lectures, dedicated to spacetime symmetry…
Higgs Boson Production in Association with Bottom Quarks
J. Campbell, S. Dawson, S. Dittmaier +7
In the Standard Model, the coupling of the Higgs boson to b quarks is weak, leading to small cross sections for producing a Higgs boson in association with b quarks. However, Higgs…
The Standard Model and the Top Quark
S. Willenbrock
The top quark is one of the least well-studied components of the standard model. In these lectures I discuss the expected properties of the top quark, which will be tested at the F…
