D1.00001: The dawn of gravitational-wave astronomy Invited Speaker: Marco Cavaglia In 1916 Albert Einstein demonstrated that the theory of general relativity allows for wave-like solutions. Although there is indirect proof of the existence of gravitational waves, their direct detection eluded us for a hundred years. The Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) is the world leading scientific experiment for the detection of astrophysical gravitational waves. The Advanced LIGO instruments became operational in September 2015 and are now collecting data at unprecedented sensitivities. It is widely expected that Advanced LIGO will soon provide the first direct detection of gravitational waves. Detection and measurement of gravitational waves will open the way to new astronomical observations and probe fundamental physics. This will be a momentous event that will mark the beginning of a new field: gravitational-wave astrophysics. In this talk I will present an overview of LIGO science and discuss the prospects of this nascent field. [Preview Abstract] |

D1.00002: Recent Results from the Belle $e^+e^-$ Experiment Invited Speaker: Himansu Sahoo In this talk, I will review the recent results from the Belle experiment at the KEK laboratory in Tsukuba, Japan. This experiment collected the worlds largest data sample of $B$ mesons using $\Upsilon(4S)$ decays at the KEKB asymmetric-energy $e^+e^-$ collider. I will present the recent results on $CP$ asymmetry measurements in $B$ decays sensitive to the unitarity triangle, radiative decays, and searches for new physics using the full data sample collected by the experiment. This experiment is currently being upgraded and aims at accumulating 40x more $e^+e^-$ collision data. In this presentation, I will also highlight the this future Belle II facility and its main physics opportunities. [Preview Abstract] |

D1.00003: First Results from the NovA Experiment Invited Speaker: Alexander Radovic The observation of neutrino oscillation provides evidence of physics beyond the standard model, and the precise measurement of those oscillations remains an important goal for the field of particle physics. NO$\nu $A will soon be one of the foremost experiments in that field. Taking advantage of a two-detector technique, a tightly focused off-axis view of the NuMI neutrino beam, and a pair of finely instrumented liquid scintillator detectors, NO$\nu $A is in a prime position to contribute to precision measurements of the neutrino mass splitting, mass hierarchy, and delta cp.This presentation will describe the goals and design of the NO$\nu $A experiment, show first results obtained whilst the detectors where still being constructed, and outline what to expect from NOvA in the coming years.

D1.00004: Physics of the Higgs Boson: Developing Broad Understanding in the Post-Discovery Era Invited Speaker: Christopher Neu The discovery in 2012 of a Higgs boson at the ATLAS and CMS experiments was a pivotal moment in the decades-long pursuit of understanding the mechanism behind electroweak symmetry breaking. The focus of subsequent studies at the LHC has been the characterization of this recently-discovered particle through precision measurements of its couplings, spin, width and other properties. This characterization campaign is crucial in understanding whether this Higgs boson is consistent with the predictions of the standard model or is a harbinger of new physics. Further, direct searches for exotic Higgs production mechanisms or rare Higgs decays could reveal yet-unseen dynamics that are important for understanding the remaining open questions in particle physics. In this talk I will summarize the state of Higgs physics from the experimental perspective, focusing on results from the LHC Run 1 and with an eye towards what could be in store in Run 2.
