    RIKEN Lunch Seminar

    "P-odd Spectral Density at Weak Coupling: Photon Emission and Second"

    Presented by Ho-Ung Yee, University of Illinois at Chicago

    12:30 pm, Building 510 Room 2-160

    Thursday, July 30, 2015, 12:30 pm

    Hosted by: Daniel Pitonyak

    The P-odd spectral density of current correlation functions appears in several physical observables which are related to chiral anomaly, and is a sensitive probe of microscopic dynamics which is less protected by symmetry alone. We discuss two examples of their appearance: photon emission and the second order transport coefficient from chiral anomaly. We describe leading order weak coupling computations for these examples.

    Nuclear Theory/RIKEN seminar

    "Generalized Landau-level representation for spin-1/2 fermions and its applications"

    Presented by Igor Shovkovy, Arizona State University

    2 pm, Small Seminar Room, Bldg. 510

    Friday, July 31, 2015, 2:00 pm

    Hosted by: Soeren Schlichting

    I will discuss the recently proposed generalized Landau-level representation for charged fermions in an external magnetic field. After demonstrating its key advantages over the other existing representations, I will mention several of its applications. One of them is the quantum Hall effect in graphene, where the new representation is essential for a sufficiently detailed theoretical description, in which all the dynamical parameters are running functions of the Landau-level index. The other application is the chiral asymmetry induced in dense relativistic matter in an external magnetic field. The quantitative measure of such an asymmetry is the chiral shift parameter that measures a relative shift of the longitudinal momenta (along the direction of the magnetic field) in the dispersion relations of opposite chirality fermions. Using the language of solid state physics, the corresponding ground state of dense relativistic matter could be interpreted as a Weyl metal state. Incidentally, the exact same mechanism also works in real Dirac metals.

    HET/RIKEN seminar

    "Higgs coupling deviations, vacuum stability and new bosons at the TeV scale"

    Presented by Raffaele D'Agnolo, Institute for Advanced Study

    2 pm, Small Seminar Room, Bldg. 510

    Wednesday, August 5, 2015, 2:00 pm

    Hosted by: Chien-Yi Chen

    Higgs coupling measurements can shed light on the nature of electroweak symmetry breaking. However it is not trivial to go beyond generic intuitions, such as the expectation that natural theories generate large deviations, and make precise statements. In this talk I will show in a model independent way that measuring deviations at the LHC implies the existence of new bosons between a few TeV and a few hundred TeV. This is true in general, including theories where new fermions produce the deviations.

    Presented by Andreas Gocksch

    Hosted by: Robert Pisarski

    After 10 years of research in High Energy Theory this BNL graduate ('83-'85 and '88-'93) followed the call of Wall Street. In my talk I reflect on over 20 years in the financial industry with an emphasis on highlighting possible career choices for young people that might one day be faced with searching for a "life after Physics". Along the way I also hope to leave the audience with an understanding of some basic facts about Finance and an appreciation for the utility of the physicist's toolkit in the "real world".

    Joint Nuclear Physics and Particle Physics Seminar

    "Understanding the nature of neutrinos via neutrinoless double-beta decay"

    Presented by Wenqin Xu, Los Alamos National Laboratory

    11 am, Small Seminar Room, Bldg. 510

    Tuesday, September 8, 2015, 11:00 am

    Hosted by: Jin Huang

    Neutrinos provide a critical portal to physics beyond the Standard Model, yet the nature of neutrinos is largely unknown, including the neutrino mass hierarcy and if neutrinos are Majorana particles. Majorana particles are fermions that are their own antiparticles. Neutrinos being Majorana particles would explicitly violate lepton number conservation, and would pave the way to understand the matter-antimatter asymmetry in the universe. Neutrinoless double-beta (0 ) decay is a hypothesized process where two neutrons decay into two protons and two electrons simultaneously without emitting neutrinos. It is possible only if neutrinos are Majorana particles, and it is the only feasible way to experimentally establish the Majorana or Dirac nature of neutrinos. The observation of 0 decay would also provide complementary information related to neutrino masses. After decades of experimental e orts, the next generation 0 decay experiments will have a signi cant discovery potential to observe 0 decay, if neutrinos are indeed Majorana particles. In this talk, we will discuss the physics of neutrinoless double beta decay and review the experiments searching for it. We will focus on the Majorana Demonstrator, a 40-kg modular Germanium detector array, which searches for 0 decay in 76Ge and aims at demonstrating a path forward to next generation 0 decay experiments.
