Anomalous Higgs Yukawa Couplings

In the standard model, the Higgs boson $h$ couples to the quarks and charged leptons according to the well-known formula $(m_\psi/v) h \bar{\psi}\psi$, where $\psi$ = quark (q) or lepton (l) and $v$ = 246 GeV is its vacuum expectation value. Suppose $m_\psi$ is of radiative origin instead, then the effective $h \bar{\psi}\psi$ Yukawa coupling will not be exactly $m_\psi/v$. We show for the first time quantitatively how this may shift the observed branching fraction of $h \to \bar{b}b$ and $h \to \tau^+ \tau^-$ upward or downward. Thus the precision measurements of Higgs decay to fermions at the Large Hadron Collider, due to resume operation in 2015, could be the key to possible new physics.Comment: 13 pages, 7 figures, version to appear in EP

Scotogenic Inverse Seesaw Model of Neutrino Mass

A variation of the original 2006 radiative seesaw model of neutrino mass through dark matter is shown to realize the notion of inverse seesaw naturally. The dark-matter candidate here is the lightest of three real singlet scalars which may also carry flavor.Comment: 10 pages, 2 figures, version to appear in PL

ICO-Mark App Users Guide - version 1.3

This is the user\u27s guide for the ICO Mark app. ICO Mark is a tablet- and phone-based application (app) developed for forest managers and forestry field crews to spatially monitor and map forest structure. ICO Mark relies on the Individuals-Clumps-Openings approach to characterizing dry forest spatial patterning, where forests are composed of varying proportions and sizes of individual trees, clumps of trees, and treeless openings. ICO Mark allows users to track individual trees and clumps for both marking pre-harvest, and for monitoring conditions post-harvest.https://scholarworks.umt.edu/ico/1001/thumbnail.jp
