Book Description
We present recent results of searches for exotic photons at CDF II. In the first signature-based search, we search for anomalous production of two photons with additional energetic objects. The results are consistent with the standard model expectations. In the second analysis, we present a signature-based search for anomalous production of events containing a photon, two jets, of which at least one is identified as originating from a b quark, and missing transverse energy. We find no indications of non-standard model phenomena. Finally, a search for a fermiophobic Higgs in the diphoton final state is presented. Since no evidence of a resonance in the diphoton mass spectrum is observed we exclude this Higgs boson with mass below 106 GeV/c2 at a 95% confidence level.

Book Description
We report recent results in CDF searches for rare and exotic processes. In a signature-based search, we examine the diphoton dataset for additional energetic objects. In a second signature-based search, we search for anomalous production of a photon, a b-tagged jet, and missing E{sub T}. Finally, we search for a Fermiophobic Higgs in the two-photon decay mode, and conclude this Higgs must have mass greater than 106 GeV/c2, at 95% confidence level.

Book Description
The Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI) was founded at Nagoya University in 2010 under the directorship of T Maskawa, in celebration of the 2008 Nobel Prize in Physics for M Kobayashi and T Maskawa, both who are alumni of Nagoya University. In commemoration of the new KMI building in 2011, the KMI Inauguration Conference (KMIIN) was organized to discuss perspectives of various fields OCo both theoretical and experimental studies of particle physics and astrophysics OCo as the main objectives of the KMI activity.This proceedings contains a welcome address by T Maskawa conveying his hopes for KMI to create new revolutionary directions in the spirit of Shoichi Sakata, a great mentor of both Maskawa and Kobayashi. Invited speakers, world-leading scientists in the fields, and the young scientists at KMI contributed to this volume containing theoretical studies of strongly coupled gauge theories in view of LHC phenomenology, string theory approach and lattice studies as well as hot/dense QCD system, and also super-symmetric GUT models, etc., together with experimental studies of LHC physics, B physics, neutrino physics and the related astrophysics and cosmology. The volume yields a unique synergy of particle physics and astrophysics, closely related to the main activity of KMI encompassing particle theory (including lattice computer simulations), particle physics experiments, cosmology, and astrophysics observations."

Book Description
A brief review of searches for physics beyond the Standard Model with photons using the CDF detector at the Tevatron is given here. These include searches for supersymmetry, extra dimensions, excited electrons and W/Z+[gamma] production, as well as anomalous photon production. Recent results from CDF Run II experiment are presented, but some results from Run I are also reviewed.

Book Description
The Lepton-Photon symposiums ? as represented by the contributions in this volume ? are among the most popular conferences in high energy physics since they give an in-depth snapshots of the status of the field as provided by leading experts.The volume covers the latest results on flavor factories, quantum chromodynamics (QCD), electroweak physics, dark matter searches, neutrino physics and cosmology, from a phenomenological point of view. It also offers a glimpse of the immediate future of the field through summaries on the status of the next generation of high energy accelerators and planned facilities for astroparticle physics.The review nature of the articles makes the volume particularly useful to students, as well as being of interest to established researches in high-energy physics and related fields.
