Discovering a light Higgs boson with light
We evaluate the prospects for detecting a non-standard light Higgs boson with a significant branching ratio to two photons, in run II of the Fermilab Tevatron. We derive the reach for several channels: 2{gamma} inclusive, 2{gamma}+1 jet, and 2{gamma}+2 jets. We present the expected run II limits on the branching ratio of h{yields}{gamma}{gamma} as a function of the Higgs boson mass, for the case of ''bosonic,'' as well as ''top-color'' Higgs bosons.

Production mechanism of the X(1740) meson
Abstract New data from π - p charge-exchange at 38 GeV/ c confirm the existence of the narrow X (1740) meson, observed in its ηη decay mode. The upper limit on its width is 80 MeV. It is not observed decaying into either η'η or π 0 π 0 . This meson is produced in charge-exchange by a mechanism other than OPE with a nucleon isobar (probably Δ(1232)), and not with a neutron.

Collider searches for extra dimensions
Searches for extra spatial dimensions remain among the most popular new directions in our quest for physics beyond the Standard Model. High-energy collider experiments of the current decade should be able to find an ultimate answer to the question of their existence in a variety of models. Until the start of the LHC in a few years, the Tevatron will remain the key player in this quest. In this paper, we review the most recent results from the Tevatron on searches for large, TeV{sup -1}-size, and Randall-Sundrum extra spatial dimensions, which have reached a new level of sensitivity and currently probe the parameter space beyond the existing constraints. While no evidence for the existence of extra dimensions has been found so far, an exciting discovery might be just steps away.

Interplay and Characterization of Dark Matter Searches at Colliders and in Direct Detection Experiments
In this White Paper we present and discuss a concrete proposal for the consistent interpretation of Dark Matter searches at colliders and in direct detection experiments. Based on a specific implementation of simplified models of vector and axial-vector mediator exchanges, this proposal demonstrates how the two search strategies can be compared on an equal footing.
