      The postulation of a Hidden Sector to complement the Standard Model offers elegant solutions to one of the most intriguing questions in elementary particle physics, being the particle nature of dark matter. The discovery of a fundamental scalar particle compatible with the Higgs boson paved the way for looking for dark matter with novel methods. In this contribution, I will review recent...

      Arun Tadepalli
      05/10/2016, 14:40
      The SeaQuest E906 experiment is a fixed target Drell-Yan experiment which is aimed at studying the anti-quark distributions in the nucleon and nuclei. 120 GeV protons from the Main Injector at Fermilab could also be used to search for massive dark gauge bosons or dark photons that could be generated when a proton beam dump interacts with a 5m long Fe beam dump. SeaQuest takes advantage of...

    20. 38. Direct Search for Dark Photon and Dark Higgs in E-1067 at Fermilab
      Ming Xiong Liu (Los Alamos National Laboratory)
      05/10/2016, 15:00
      Through kinetic mixing, the postulated dark photon and dark Higgs particles could be produced in the Drell-Yan like q-qbar and gluon-gluon fusion processes in high energy proton + nucleus collisions, respectively. Starting from 2017, the E-1067 experiment at Fermilab will carry out the first direct search for such particle productions in the mass range 0.2 ~ 10 GeV in parasitic with the...

    23. 28. Gravitational Wave Signals of Cosmological Phase Transitions
      Geraldine Servant (CERN)
      05/10/2016, 16:40
      Strong first-order cosmological phase transitions produce a stochastic gravitational wave background. We discuss the resulting contributions from bubble collisions, magnetohydrodynamic turbulence, and sound waves, and estimate the total corresponding signal predicted in gravitational waves. We demonstrate that LISA is able to probe many well-motivated scenarios beyond the Standard Model of...

    31. 39. Recent results and prospects on Dark Interactions from CERN
      Gianluca Lamanna
      06/10/2016, 14:00
      Kaon experiments at CERN (NA48/2 and NA62) study decays in flight of secondary charged kaons produced by 400 GeV/c protons from the SPS accelerator hitting a Beryllium target. The NA48/2 experiment was exposed to 2x10^{11} kaon decays in 2003-2004, and NA62 is set to surpass this figure by a factor of 50 in 2016-2018. Prospects for the dark photon, heavy neutral lepton and axion-like particle...

    32. 40. Simplified DM models: a case with t-channel colored scalar mediators
      Alexander Natale (KIAS)
      06/10/2016, 14:20
      The general strategy for dark matter (DM) searches at colliders currently relies on simplified models in order to describe the interactions between the Standard Model (SM) and DM and potential collider signatures at the LHC. A recently proposed UV-complete simplified model with t-channel mediators improves the existing simplified DM models in two important respects: (i) the full SM gauge...

    33. 41. Dark matter models with two mediators
      Michael Duerr (DESY)
      06/10/2016, 14:40
      A reliable comparison of different dark matter searches requires models that satisfy certain consistency conditions like gauge invariance and perturbative unitarity. These conditions can easily be satisfied in U(1)' extensions of the Standard Model, where a fermionic dark matter candidate as well as a new Z' gauge boson obtain their mass from the spontaneous breaking of the U(1)' by a...

      Igal Jaegle (University of Hawaii at Manoa)
      06/10/2016, 15:00
      The dark photon, A′, the dark Higgs boson, h′, and the dark vector gauge boson, U', are hypothetical constituents featured in a number of recently proposed Dark Sector Models. We will present searches for these particles in the Belle data and discuss prospects in the future Belle II data.

    35. 43. Search for Dark Photons at LHCb
      Wei Xue (MIT)
      06/10/2016, 15:20
      Dark photons appear in many well-motivated dark matter scenarios, leading to a worldwide effort to search for them. We propose some novel search methods for dark photons at the LHCb experiment. In this talk, I will focus on the inclusive search for dark photons at the LHCb experiment based on both prompt and displaced di-muon resonances. The dark photon rate can be directly inferred from the...

    36. 45. Astrophysical Signatures of Dissipative Dark Matter
      Eric Kramer (Harvard University)
      06/10/2016, 16:15
      After nearly a century of searching, the nature of dark matter continues to elude us.While Ockham's razor may at face value want a favor a dark sector with one component, the complexity of the visible sector urges us to consider dark sectors with multiple components, including possibly dissipative interactions. In a galaxy like the Milky Way, these interactions would lead to cooling of...

    37. 47. Updated Bounds on Light Hidden Sectors in Supernovae
      Samuel McDermott (YITP)
      06/10/2016, 16:35
      Supernova 1987A created an environment of extremely high temperatures and nucleon densities, providing an opportunity to set bounds on a wide range of theories of new physics. We present corrected bounds on hidden sector models, incorporating a wide range of new physical effects on the production, including some novel corrections to the high-mixing-angle calculation. These bounds dramatically...

    38. 49. "Lattice Gauge Theory insights on Dark Matter
      Enrico Rinaldi (BNL)
      06/10/2016, 16:55
      Models of composite dark matter, originating from a new strongly coupled dark sector, have a very interesting phenomenology. To make robust predictions in these models one often need to investigate non-perturbative effects due to the strong self interactions. Lattice field theory methods and numerical simulations are well suited for this task and contribute to a solid uncertainty...

    39. 46. The search for a dark Z boson with Machine Learning
      Savannah Thais (Yale University)
      06/10/2016, 17:15
      The existence of a dark sector vector boson (Zd) is well motivated by theory and experiment; models add a U(1) gauge symmetry to the standard model which introduces a new gauge field Zd with kinetic mixing epsilon (I'll add the actual symbol) and a Higgs doublet with mass mixing kappa. We can thus use the Higgs as a portal to look for such a particle at the LHC. In particular, we can expand...

    40. 50. Respect the ELDERs
      Yu-Dai Tsai (Cornell University)
      06/10/2016, 17:35
      We present a novel dark matter candidate, an elastically decoupling relic, which is a cold thermal relic whose present abundance is determined by the cross section of its elastic scattering on standard model particles. The dark matter candidate is predicted to have a mass ranging from a few to a few hundred MeV, and an elastic scattering cross section with electrons, photons and/or neutrinos...

      Prof. Ashutosh Kotwal (Duke University)
      07/10/2016, 09:40
      The Large Hadron Collider has been a grand success with the discovery of the Higgs boson, with bright prospects for additional discoveries since the recent increase in collider energy and the anticipated large datasets. Big open questions such as the nature of dark matter, the origin of the matter-antimatter asymmetry in the Universe, and the theoretical puzzle of the finely-tuned parameters...
