Prof. Leonardo Giusti (University of Milano Bicocca)14/07/2015, 09:15Chiral SymmetryTalkI review recent progress achieved on the lattice in the understanding of chiral symmetry breaking in QCD. Emphasis is given to recent computations of the spectral density of the Dirac operator and of the topological susceptibility.Go to contribution page

Dr YU NAKAYAMA (Caltech)14/07/2015, 10:00Theoretical DevelopmentsTalkThere has been a longstanding debate if the chiral phase transition in two-flavor massless QCD is the first order or the second order. The previous arguments based on epsilon expansions, large N expansions, functional renormalization group, and Monte-Carlo simulations had been all inconclusive with shortcomings. If it were the second order phase transition, there should exist a corresponding...Go to contribution page

Dr Tatsumi Aoyama (KMI, Nagoya University)14/07/2015, 11:00TalkThe anomalous magnetic moment (g-2) of the electron has played the central role in testing the validity of quantum electrodynamics (QED) as well as the standard model of particle physics. The test has been further improved, which was made possible by the complete evaluation of the tenth-order term in the perturbation theory of QED, together with the latest measurement of the electron g-2 by...Go to contribution page

Taku Izubuchi (RIKEN BNL Research Center)14/07/2015, 11:45Hadron StructureTalkThere has been much progress in studies of the physics of low energy, precision observables in the flavor neutral sector using Lattice QCD, especially on the lepton anomalous magnetic moments ($g-2$) and nucleon electric dipole moments. The current status of these studies is reviewed, and remaining challenges and new ideas are discussed.Go to contribution page

Dr James Zanotti (University of Adelaide)15/07/2015, 09:00Hadron StructureTalkHere we review the progress made in understanding the internal structure of hadrons in terms of the gluonic and quark constituents. Recent results for standard observables such as the nucleon axial charge, electromagnetic form factors and quark momentum fraction will be summarised, before turning our attention to more challenging quantities, including quark disconnected contributions and...Go to contribution page

Dr Andreas Juettner (University of Southampton)15/07/2015, 09:45Hadron Spectroscopy and InteractionsTalkFor quite some time now simulations of lattice QCD have allowed for predicting a basic set of light flavour quantities reliably and with increasingly high precision. The field has started to move on: Advances in field theory, algorithms and computing for the first time allow to address more complicated problems like for example hadronic and rare kaon decays, the kaon mass-difference or the...Go to contribution page

Dr Maxwell Hansen (University of Mainz)15/07/2015, 11:30Hadron Spectroscopy and InteractionsTalkScattering and transition amplitudes with three-hadron final states play an important role in nuclear and particle physics. In order to predict such quantities using Lattice QCD, formalism is required to overcome the limitations of Euclidean time and finite volume. In this talk I will focus on extensions of Luescher's work relating the finite-volume energy spectrum to physical scattering...Go to contribution page

Dr Christopher Kelly (RBRC, Brookhaven National Laboratory)15/07/2015, 12:00Weak Decays and Matrix ElementsTalkWe discuss our recent publication [arXiv:1505.07863] of the first lattice QCD calculation of the complex kaon decay amplitude A_0 with physical kinematics, using a single 32^3 x 64 domain wall ensemble with G-parity spatial boundary conditions. We obtain approximate agreement with the experimental value for Re(A_0), which serves as a test of our method. Our prediction of Im(A_0) can be used to...Go to contribution page

Prof. Mithat Unsal (North Carolina State University)17/07/2015, 09:00Theoretical DevelopmentsTalkResurgent trans-series provide a novel mathematical formalism to unify perturbative and non-perturbative physics, leading to new insights into the general structure of quantum theories. I will review the main ideas with some illustrative examples. In many quantum mechanical systems, all orders non-perturbative data is encoded into perturbation theory, and it can be decoded. In QFTs, there...Go to contribution page

Prof. Francesco Sannino (CP3-Origins & DIAS, University of Southern Denmark)17/07/2015, 09:45Physics Beyond the Standard ModelTalkCirca 95% of the universe is made of unknown forms of matter and energy, while to describe the remaining 5% one needs at least three fundamental forces, i.e. Quantum Electrodynamics, Weak Interactions and Quantum Chromo Dynamics (QCD). Furthermore strong interactions are responsible for creating the bulk of the bright mass, i.e. the 5%. It is therefore natural to expect that to correctly...Go to contribution page

Prof. Toru Iijima (KMI, Nagoya University)17/07/2015, 11:00TalkIn this talk, we discuss the status and future prospect in B physics, focusing on the SuperKEKB/Belle II experiment at KEK, with the target peak luminosity of 8 \times 10^35 cm^-2s^-1. This enables us to study decays of heavy flavor particles, B and D mesons as well as \tau leptons, at the order of O(10^10) per year, and to search for New Physics through processes sensitive to presence of...Go to contribution page

Prof. Carlos Pena (Universidad Autónoma de Madrid and IFT-UAM/CSIC)17/07/2015, 11:45Hadron Spectroscopy and InteractionsTalkI will review recent progress in lattice computations relevant for B- and charm physics. Emphasis will be put on the interplay with the upcoming new generation of experimental results.Go to contribution page

Prof. Harvey Meyer (Johannes Gutenberg-University Mainz)18/07/2015, 13:00Nonzero Temperature and DensityTalkI will review the status of calculations of thermodynamics quantities, spatial correlation lengths and real-time properties of strongly interacting matter at non-zero temperature. An attempt at a synthesis will be made. Quark number susceptibilities will not be covered here.Go to contribution page

Dr Szabolcs Borsanyi (University of Wuppertal)18/07/2015, 13:45Nonzero Temperature and DensityTalkFluctuations of conserved charges in a grand canonical ensemble can be calculated as derivatives of the free energy with respect to the respective chemical potential. They are directly related to experimentally available observables that describe the hadronization in heavy ion collisions. The same derivatives can be used to extrapolate zero density results to finite chemical potential. We...Go to contribution page

Dr Luigi Scorzato18/07/2015, 14:15Nonzero Temperature and DensityTalkIn this talk I will review the proposal to formulate quantum field theories (QFTs) on a Lefschetz thimble, which was put forward to enable Monte Carlo simulations of lattice QFTs affected by a sign problem. First I will review the theoretical justification of the approach, and comment on some open issues. Then, I will review the algorithms that have been proposed and are being tested to...Go to contribution page

Dr Daisuke Kadoh (KEK)18/07/2015, 15:15Physics Beyond the Standard ModelTalkNon-perturbative investigations of supersymmetry and superstring theory through lattice simulations are promising research directions. In this talk, I will review the recent progress in lattice supersymmetry, in particular, the numerical verification of the gauge/gravity duality.Go to contribution page

Dr Anna Hasenfratz (University of Colorado)18/07/2015, 15:45Physics Beyond the Standard ModelTalkThe discovery of the Higgs boson in 2012 completed the Standard Model but many puzzles remain. Composite systems where the Higgs boson is a bound state of some new fermion species are viable models to describe beyond-SM phenomenology, but are most likely strongly coupled and require non-perturbative investigations. In this talk I will review recent lattice calculations that investigate...Go to contribution page
