  1. 36. Dark Axion Portal

  2. 37. Searching for Dark Photons at the LHeC and FCC-he

    Extensions of the Standard Model (SM) gauge group with a new $U(1)_X$ predict an additional gauge boson. Through kinetic mixing with the SM photons featured by a coupling $\epsilon$, the ensuing so-called dark photons $\gamma'$, which acquire mass as a result of the breaking of the gauge group $U(1)_X$, can interact with the SM field content. These massive dark photons can therefore decay to...

  3. 38. Axion-photon-dark photon oscillation and its implication for 21 cm observation
    Seokhoon Yun (KIAS)
    04/12/2019, 15:00

    We examine the resonant conversion of axion-like particle (ALP) or dark photon to the electromagnetic photon in the early Universe, which takes place due to the ALP-photon-dark photon oscillations in background dark photon gauge fields. It is noted that the corresponding conversion probability can have an unusual spectral feature which allows strong conversion at low frequency domain, but has...

  4. 11. Higgs inflation: updated
    Seong Chan Park (Yonsei University)
    05/12/2019, 14:00

    Higgs inflation is the best fitting model of cosmological inflation after the Planck data. I would like to discuss some recent discussions on fine-tuning, unitarity, violent preheating, and primordial black hole formation in Higgs inflation.

  5. 12. Magnetogenesis from rotating scalar: à la scalar chiral magnetic effect
    Chang Sub Shin (IBS-CTPU)
    05/12/2019, 14:30

    The chiral magnetic effect is a phenomenon that an electric current parallel to the magnetic fields is induced in the presence of the chiral asymmetry in the fermionic system. In this talk, I would like to point out that the electric current induced by the dynamics of a pseudo scalar field that anomalously couples to electromagnetic fields can be interpreted as a similar effect in the scalar...

  6. 13. Neutrino self-interaction in the signals from blazar TXS 0506+056
    Yongsoo Jho (Yonsei University)
    05/12/2019, 15:00

    Even though conventional leptonic or lepto-hadronic models of blazar successfully explain the observed electromagnetic component of the flaring signal from the Blazar TXS 0506+056 in a large range of energy window 𝐸𝛾∈(10−1eV,102 GeV), the predicted neutrino flux is too small to be consistent with the IceCube observation at 𝐸𝜈∼300 TeV. We show that a sizable self-interaction of neutrinos with a...
