42. Precision Prediction for Higgs Production at Small Transverse Momentum

Dr HuaXing Zhu (MIT)

2/2/17, 4:00 PM

In this talk I will discuss a precision calculation for transverse-momentum distribution of the Higgs boson at the LHC, in the framework of Soft-Collinear Effective Theory. Thanks to the recently calculated three-loop anomalous dimension for rapidity divergence, the large logarithms of $Q_T$ can be resummed to approximate N$^3$LL accuracy, including the full tower of logarithms at N$^3$LO....

41. Inclusive jets and their substructure within SCET

Dr Felix Ringer (Los Alamos National Laboratory)

2/2/17, 4:25 PM

We review the treatment of inclusive jets and their substructure within Soft Collinear Effective Theory (SCET). The cross section for these observables can be written in a factorized form in terms of hard functions and so-called semi-inclusive jet functions. The semi-inclusive jet functions satisfy renormalization group (RG) equations which take the form of standard timelike DGLAP evolution...

66. Transverse Momentum Dependent Fragmenting Jet Functions with Applications to Quarkonium Production

Thomas Mehen (Duke University)

2/2/17, 4:50 PM

We introduce the transverse momentum dependent fragmenting jet function (TMDFJF), which appears in factorization theorems for cross sections for jets with an identified hadron. These are functions of z, the hadron's longitudinal momentum fraction, and transverse momentum, p_T, relative to the jet axis. In the framework of Soft-Collinear Effective Theory (SCET) we derive the TMDFJF...

38. Transverse momentum spectra at the LHC

Dr Varun Vaidya (LANL)

2/2/17, 5:15 PM

Transverse momentum spectra of gauge bosons are the primary observables that involve a new class of generalized PDF's called TMDPDF's( Transverse momentum dependent pPDF's) that probe the 3 -dimensional structure of hadrons. Two of the most important of these observables are the Higgs and Drell-Yan transverse momentum spectra. I will talk about the precision calculation of these cross-sections...
