Rest Frame Subjet Algorithm With SISCone Jet For Fully Hadronic Decaying Higgs Search

The rest frame subjet algorithm is introduced to define the subjets for the SISCone jet. Using it, an IR and collinear safe jet shape observable N-subjettiness, $\tau_N^{j}$, is defined to discriminate the fat jet from a highly boosted color singlet particle decaying to N partons and the QCD jet. Using rest frame subjets and $\tau_2^{j}$ on dijets from highly boosted $\it H / W / Z$ bosons through $pp \to \it H W$, $\it H Z$, we found that statistical significance of the signal is about $2 \sigma$ at the LHC with $\mathcal{L} \sim 30 \mathrm{fb^{-1}}$ at 14 \tev.Comment: 5 pages, 3 figures. v2: references added, minor corrections.

The measurement of farmers' risk attitudes using a non-structural approach

This study estimates farmers' risk attitudes in Missouri using a non-structural approach over time. The non-structural approach proposed by Antle (1989) allows for multiple outputs and various types of risk faced by farmers and doesn't require specific functional forms for utility or production. This approach can also provide farmers' risk attitudes over time. The results show that farmers' risk attitudes are risk loving and change over time, while farmers' risk attitude is generally assumed to be risk averse and very stable over time. Since this approach has the different definition of risk attitude, the results of this study may be a bit different from previous studies.risk attitude, risk preference, nonstructural approach, structural approach, Agribusiness, Community/Rural/Urban Development, Farm Management,
