"Another addition to the U(1) jungle"
ABSTRACT:

In a truly model independent approach we review the class of anomaly free U(1) extensions of the SM. Parametrising the extension in terms of three observable quantities, namely, MZ′, the Z-Z′ mixing angle (alphaZ) and the extra U(1) effective gauge coupling (g'), which absorb all model dependence, we proceed to draw exclusion contours in the parameter space. For the exclusion limits we use the latest LHC DY data, unitarity, and electron--muon-neutrino scattering data. The DY data turns out to be the most stringent, but the other two constraints have situational merits, as we discuss.

"Recent Results from the NOvA Neutrino Experiment"
 
 Slideshow (PDF)
ABSTRACT:

Neutrinos are abundant fundamental particles throughout the universe; second-most only to the photon. They undergo a phenomenon called neutrino oscillation whereby they change flavor from one type to another as they travel. The NOvA experiment seeks to elucidate further understanding of this phenomenon utilizing Fermilab's NuMI neutrino beam and two detectors to observe neutrino interactions: a 300 ton near detector underground at Fermilab, IL and a 14 kton far detector in Ash River, MN.

The NOvA experiment has recently produced updated neutrino oscillation measurements as well as its first antineutrino oscillation results and these are presented herein.

"Frontiers in Multi-Messenger Astrophysics at the interface of Numerical Relativity and Deep Learning"
ABSTRACT:

Gravitational wave observations with the LIGO and Virgo detectors from a succession of mergers of black holes are a triumph of experimental and theoretical physics, and data science.  Similarly, the observation of two colliding neutron stars in gravitational waves and light heralds the era of Multi-Messenger Astrophysics. In this talk I outline a vision to drive innovation at the interface of gravitational wave astrophysics, large scale astronomical surveys, deep learning and large scale computing to address outstanding theoretical and data science challenges to realize the full potential of Multi-Messenger Astrophysics.

"Top quark physics at the precision frontier"
ABSTRACT:

The talk will highlight latest results on top quark physics at CMS employing pp collision data at a center-of-mass energy of 13 TeV. New results from other experiments and center of mass energies will also be discussed. With millions of top quarks already collected at the LHC top quark physics enters the precision era. Differential cross section measurements and top quark property measurements, in particular angular correlations, are challenging the Standard Model predictions. The intimate connection of the top quark to the Higgs Boson is scrutinized by highly precise direct measurements of the top quark mass, with alternative approaches entering the precision realm as well. The talk concludes with implications for the SM and an outlook towards the ultimate precision frontier at the high-luminosity phase of the LHC.
