Kiwoon Choi (CTPU, IBS)13/02/2018, 09:30I discuss a late-time magnetogenesis scenario, which takes place after the epoch of electron/positron annihilation. It involves an ultralight axion-like particle, constituting the dark matter of the Universe, and a dark U(1) gauge boson introduced to bypass the obstacle from the relatively high conductivity of the cosmic plasma.Go to contribution page

Tom Melia (Kavli IPMU)13/02/2018, 10:00I’ll describe a parameterisation of phase space where the physical (on-shell & momentum conserving) manifold, upon which observables have support, is identified with a coset space for the breaking of a particle number symmetry. I’ll talk about its applications to monte carlo simulation and partial wave analyses.Go to contribution page

Fuminobu Takahashi (Tohoku University)13/02/2018, 11:00The QCD axion may be coupled to a hidden sector. As an example, I will discuss two scenarios in which the QCD axion is coupled to a hidden photon. In the first case, the axion is coupled to massless hidden photons, and such a coupling is known to induce tachyonic instabilities if the coupling is sufficiently strong. I will explain how the tachyonic preheating affects the final axion abundance...Go to contribution page

Alessandro Strumia (Pisa U & INFN & CERN)14/02/2018, 09:00We explore the possibility that Dark Matter is the lightest hadron made of two stable color octet Dirac fermions $\Q$. The cosmological DM abundance is reproduced for $M_\Q\approx 9.5 \TeV$, compatibly with direct searches (the Rayleigh cross section, suppressed by $1/M_\Q^6$, is close to present bounds), indirect searches (enhanced by $\Q\Q+\bar\Q\bar\Q\to \Q\bar\Q+\Q\bar\Q$ recombination),...Go to contribution page

Ibarra Alejandro (Technical University of Munich)14/02/2018, 09:30The interpretation of any experiment probing the dark matter distribution inside the Solar System is subject to our ignorance of the local dark matter density and velocity distribution, as well as our ignorance of the nature and strength of the dark matter-nucleon interaction. In this talk we present new ideas to interpret the outcome of direct detection experiments without making assumptions...Go to contribution page

Ning Zhou (Shanghai Jiao Tong University)14/02/2018, 10:00PandaX experiment, located at China JinPing underground Laboratory (CJPL), is a 500kg scale liquid xenon dark matter direct detection experiment. With the first 98.7-day data, PandaX-II experiment obtained stringent upper limits on the spin-independent (SI) and spin-dependent (SD) WIMP-nucleon elastic scattering cross sections. Alternative models of dark matter are also explored using this...Go to contribution page

Federico Sforza (Tufts University)14/02/2018, 14:20The precise measurement of SM observables is a key element of the LHC programme, both as a probe of the fundamental properties of Nature and as a tool to improve future experimental and theoretical studies. This talk reviews the recent highlights in the measurement of SM processes, including the SM-Higgs properties, performed thanks to the ATLAS experiment.Go to contribution page

Tony Gherghetta (University of Minnesota)15/02/2018, 09:00The LHC Run II superpartner mass limits have exacerbated the tuning in supersymmetric extensions of the Standard Model. A possible way to explain this tuning is via a two-field relaxion mechanism, where the second field is identified with the inflaton. I will discuss the implications of the relaxion-inflaton dynamics for supersymmetry and inflation, as well as the prospects for detecting this...Go to contribution page

Yuji Omura (KMI, Nagoya Univ.)15/02/2018, 10:00The small quark mixing, described by the Cabibbo-Kobayashi-Maskawa (CKM) matrix in the Standard Model, may be a clue to reveal new physics around the TeV scale. We consider a simple scenario that extra particles in a hidden sector radiatively mediate the flavor violation to the quark sector around the TeV scale and effectively realize the observed CKM matrix. The lightest particle in the...Go to contribution page

Christoph Bobeth (Technical University Munich)15/02/2018, 11:00After a review of tensions in charged-current and rare B decays and their interpretation in beyond SM scenarios, we focus on some developments that aim to improve theoretical control. Progress on QED corrections to leptonic decays B_s -> mu mu and B_u -> mu nu has been made, that was required in view of the current accuracy providing in the future precision at the percent level to...Go to contribution page

Konosuke Iwamoto (University of Tokyo)15/02/2018, 11:30Non-zero mass of the neutrinos was proved by the discovery of neutrino oscillations in 1998. Further precision measurements of the neutrino oscillations lead to understanding the matter-antimatter asymmetry of the universe. This talk provides overview of neutrino oscillations and the experimental results that contribute to measuring the oscillation parameters. Recent results and the future...Go to contribution page

Matthew Reece (Harvard University)16/02/2018, 09:30I will discuss some work in progress that explores whether a mildly fine-tuned Higgs boson, as in (mini-)split supersymmetry, can have interesting or observable cosmological consequences. As moduli fields oscillate, the Higgs can respond and perhaps acquire very large values along a D-flat direction. Possible consequences involve a burst of gravitational wave production and an altered estimate...Go to contribution page

Amit Chakraborty (KEK)16/02/2018, 14:10We study squark decays beyond the Minimal Flavor Violation framework at the LHC. Considering mixing between the second and third generation squarks, we first provide the coverage of the current searches at the Run-1 and Run-2 of LHC in the context of a simplified model containing two active squark flavours. We then study the sensitivity of a dedicated search strategy involving leptons, jets,...Go to contribution page

Michelangelo Mangano (CERN)16/02/2018, 14:35The LHC performance continues to exceed expectations, and the experiments are entering a new high-statistics phase for their studies. The projections for the ultimate physics output of the LHC are being updated, and new plans are being drawn for next steps, with scenarios ranging from an energy upgrade of the LHC, to the construction of a new 100km circular collider facility. I will review the...Go to contribution page
