TL;DR: In this article, Monte Carlo (MC) event generators are heavily utilized to extract and interpret the Higgs signal, which depends on the details of the soft-gluon emission from the initial state partons in hadronic collisions.
Abstract: The search for the Higgs boson(s) is one of the major priorities at the upgraded Fermilab Tevatron and at the CERN Large Hadron Collider (LHC). Monte Carlo (MC) event generators are heavily utilized to extract and interpret the Higgs signal, which depends on the details of the soft-gluon emission from the initial state partons in hadronic collisions. Thus, it is crucial to establish the reliability of the MC event generators used by the experimentalists. In this paper, the MC based parton shower formalism is compared to that of an analytic resummation calculation. Theoretical input, predictions and, where they exist, data for the transverse momentum distribution of Higgs bosons, ${Z}^{0}$ bosons, and photon pairs are compared for the Tevatron and the LHC. This comparison is useful in understanding the strengths and the weaknesses of the different theoretical approaches, and in testing their reliability.

TL;DR: A personal view of current prospectives in particle physics is presented in this article, inspired by the contributions to this meeting, with particular emphasis laid in precision tests of the Standard Model and the search for the Higgs boson, on probes of CP violation, speculations about possible physics beyond the standard model, on neutrino masses and oscillations, on the quest for supersymmetry, on opportunities @ future accelerators, and on the ultimate phenomenological challenge oered by a Theory of Everything.

TL;DR: In this paper, the current state of the electroweak theory, making brief comments about the search for the Higgs boson and some of the open issues for the theory, is discussed.
Abstract: I quickly review the successes of quantum chromodynamics. Then I assess the current state of the electroweak theory, making brief comments about the search for the Higgs boson and some of the open issues for the theory. I sketch the problems of mass and mass scales, and point to a speculative link between the question of identity and large extra dimensions. To conclude, I return to QCD and the possibility that its phase structure might inform our understanding of electroweak symmetry breaking.
