Top Quark Yukawa Couplings and New Physics
We discuss associated production of a Higgs boson with a pair of
quarks at a future high energy collider. The process is particularly sensitive to the presence of new physics and we
consider the MSSM and models with extra dimensions at the scale as
examples.Comment: Talk given at the 5th International Collider Workshop (LCWS 2000),

Next-to-Leading Order Results for t-tbar-h Production at the Tevatron
We compute the O(alpha_s^3) total cross section for the process (p pbar -> t
tbar h) in the Standard Model, at \sqrt{s}=2 TeV. The next-to-leading order
corrections drastically reduce the renormalization and factorization scale
dependence of the Born cross section and slightly decrease the total cross
section for renormalization and factorization scales between m_t and 2m_t.Comment: 5 pages, 5 figures, REVTeX, submitted to Phys. Rev. Let
Does Interacting with Trustworthy People Enhance Mindfulness? An Experience Sampling Study of Mindfulness in Everyday Situations
Mindfulness is known to increase after meditation interventions. But might features of our everyday situations outside of meditation not also influence our mindfulness from moment-to-moment? Drawing from psychological research on interpersonal trust, we suggest that interacting with trustworthy people could influence the expression of mindfulness. And, extending this research on trust, we further suggest that the influence of trustworthy social interactions on mindfulness could proceed through two pathways: a particularized pathway (where specific interactions that are especially high (or low) in trustworthiness have an immediate influence on mindfulness) or a generalized pathway (where the typical level of trustworthiness a person perceives across all their interactions exerts a more stable influence on their mindfulness). To explore these two pathways, study participants (N = 201) repeatedly reported their current levels of mindfulness and their prior interactions with trustworthy leaders and teammates during their everyday situations using an experience sampling protocol ( = 3,605 reports). Results from mixed-effects models provide little support for the particularized pathway: specific interactions with trustworthy leaders and teammates had little immediate association with mindfulness. The generalized pathway, however, was strongly associated with mindfulnessâand remained incrementally predictive beyond relevant individual differences and features of situations. In sum, people who typically interact with more trustworthy partners may become more mindful
Note on islands in path-length sequences of binary trees
An earlier characterization of topologically ordered (lexicographic)
path-length sequences of binary trees is reformulated in terms of an
integrality condition on a scaled Kraft sum of certain subsequences (full
segments, or islands). The scaled Kraft sum is seen to count the set of
ancestors at a certain level of a set of topologically consecutive leaves is a
binary tree.Comment: 4 page
Higgs Boson Production with Bottom Quarks at Hadron Colliders
We present results for the production cross section of a Higgs Boson with a
pair of bottom/anti-bottom quarks, including next-to-leading order (NLO) QCD
corrections.Comment: 3 pages, 2 figures, uses ws-ijmpa.cls. Talk given by C.B. Jackson at
