Title: "Frontiers in Nucleon Structure"
Quantum chromodynamics offers a powerful and elegant description of one of the fundamental forces in nature. However, we remain at an early stage in being able to describe the everyday nuclear matter of the world around us in terms of the fundamental degrees of freedom in QCD, quarks and gluons. The proton, as a fundamental bound state of QCD, can serve as an excellent laboratory in which to probe the complexities of the strong force as we learn more about the very matter of which we ourselves are made.
Colliding polarized proton beams at the Relativistic Heavy Ion Collider (RHIC) offers a novel experimental method for the investigation of nucleon structure, in particular its angular momentum structure. The measurements at RHIC provide unique sensitivity to the spin contribution from the gluon field in the proton and the spin structure of the quark and anti-quark sea, as well as the transverse spin structure of the
proton, which continues to produce a number of startling effects. Highlights of the recent contributions that RHIC has made to the study of proton structure will be presented.
Looking beyond RHIC, a new facility, capable of colliding a beam of electrons with a wide range of nuclei as well as polarized protons and light ions, has been proposed: the Electron-Ion Collider (EIC) promises to usher in an era of precision measurements of QCD phenomena in nuclear matter, bringing the field to a new stage. The status and prospects of the EIC will be discussed.

Title: "Search for active neutrino disappearance in MINOS"
MINOS is a long baseline neutrino oscillation experiment with two detectors that are separated by a distance of 735 km and exposed to a high power muon neutrino beam. The experiment has reported a significant deficit of muon neutrinos at its far detector relative to the near detector through measurement of the rate of charged-current interactions. If this deficit is due solely to conversions of muon neutrinos to electron and tau neutrinos, then the rate of neutral- current (NC) interactions at the far detector remains unchanged from the non-oscillation prediction. Alternatively, if any muon neutrinos convert to a sterile state, then the NC rate would be suppressed and the reconstructed energy spectrum would be distorted. In this talk I will describe the analysis of the NC interactions from an exposure of the MINOS detectors to 2.5e20 protons on target.

Title: "Exploring the extreme universe: astronomy and particle physics with VHE gamma-rays"
Viewed at very high energies, the universe is a place of powerful astrophysical engines driving accelerators that reach far greater energies than anything built on earth. By studying the products of these accelerators (such as cosmic rays and gamma-rays), we can not only learn a great deal about the astrophysics of these sources, but probe a variety of questions in particle physics and cosmology. A new generation of imaging atmospheric Cherenkov telescopes (IACTs),designed to detect VHE (100 GeV-10 TeV) gamma-rays, has radically altered our picture of the very high-energy gamma-ray sky. One such instrument is the recently-commissioned IACT array VERITAS, which saw first light in April 2007. I will discuss results from the first two years of the VERITAS observing program and the guidance that they offer for the next few years of the VERITAS program. The impact of (and synergy with) the recently-launched Fermi satellite, which promises to similarly revolutionize gamma-ray astronomy in the 20 MeV to 300 GeV band, will also be discussed, along with long-term directions for the field.

Title: "The first CDMS five tower results and the solid xenon project"
The Cryogenic Dark Matter Search (CDMS) is originally
designed searching for Weakly Interacting Massive Particles (WIMPs)
with low-temperature crystal detectors that are able to read out both
ionization and phonon signals. However the same detector can also be
used for solar and galactic axion search. In this talk I will present
results of dark matter search, and the first results of solar and
Galactic axion search using the CDMS detectors. I will then discuss a
next generation multi-purpose detector R&D, the solid xenon project.

Title: "The IceCube Neutrino Observatory: Opportunities for Astroparticle Physics"
Neutrino astronomy offers the ability to pinpoint high energy hadronic
processes in the universe including locations of cosmic ray
acceleration. After the description of the "Cosmic particles
flowchart", I will discuss the IceCube project.
The IceCube neutrino observatory, under construction at the South Pole, consists of three sub-detectors: a 3-dimensional array of digital optical modules deployed deep in the ice, the AMANDA neutrino telescope and the surface array IceTop. I will summarize results from searches for cosmic neutrinos with the AMANDA telescope and review expected sensitivities for IceCube at various installation phases. Reliability and robustness of installation at the South Pole has been demonstrated along the past five construction seasons. On the base of the experience gained in operations at the South Pole, the extension of IceCube at the extreme ends (low and high) of the energetic region can be accomplished. I will describe the IceCube Deep Core project and connected new opportunities for astroparticle physics.

Title: "Fermilab long baseline v oscillation experiments: From MINOS to NOvA and Beyond"
First I will make a general introduction to neutrino physics, with
emphasis in neutrino oscillation physics. Then I will review in detail
the current status and results of the MINOS experiment, as well as its
future prospects. At the last part of the talk I will focus on the
remaining, challenging open questions related with neutrinos, and I
will discuss how we plan to address them with near term, NOvA, as well
as longer term, FNAL-TO-DUSEL long baseline neutrino oscillation

Title: "Search for Neutrinoless Double Beta Dacay in CUORE"
The questions concerning the nature and origin of neutrino mass are among the most pressing issues in contemporary particle physics. CUORE is a ton-scale bolometric detector which will search for the Double Beta Decay of 130Te, hence providing access to an unexplored range in the neutrino mass spectrum. CUORICINO, a 40kg prototype, has so far provided very stringent limits on the Mayorana neutrino mass.
The CUORE R&D program is focused on the assessment and reduction of the radioactive background of the detector (which is the limiting factor in its sensitivity), as well as on the manifold issues concerning the scalability of the bolometric concept. The ongoing R&D effort will allow to push the ultimate sensitivity of the CUORE experiment into the inverted hierarchy region of the neutrino mass spectrum (few tens of meV in Majorana mass).
In my talk I will report the main results from CUORICINO, the highlights of the present R&D activity and the projections for the CUORE discovery potential in a 5 years exposure window.

Title: "Neutrino Physics with SciBooNE and T2K"
In the last decade, neutrino experiments have definitively shown that neutrinos have non-zero mass and undergo flavor oscillation. The next generation of experiments will take the field from the discovery to the precision measurement phase. One crucial component of the precision era is better understanding of neutrino interaction cross sections. SciBooNE is a neutrino experiment that operated successfully at Fermilab in 2007 and 2008, and is making the most precise cross section measurements to date near 1 GeV. I will describe the experiment and SciBooNE's role in the global neutrino program; I will also present the first physics analysis and prospects for future measurements.

Title: "Electron-proton collisions at sqrt(s) = 320 GeV -- building the legacy of HERA"
For fourty years, deep inelastic scattering has been an important tool to investigate the structure of matter at subnuclear distances. Following on a long sequence of fixed-target experiments, HERA was the first, and so far the only, electron-proton collider. It operated at the DESY laboratory in Hamburg, Germany, from 1992 - 2007. The ongoing analysis of the recorded data will go on for several more years. In this talk the fundamental questions tackled by the HERA data will be discussed. Some recent key results on proton structure, precision tests of QCD as well as the Electro-Weak sector of the Standard Model of particle physics, and on searches for non-Standard Model processes will be presented.
