Probing Muonic Forces with Neutron Stars Binaries / Dror, Jeff A. (LBL, Berkeley ; UC, Berkeley) ; Laha, Ranjan (CERN) ; Opferkuch, Toby (CERN)
We show that gravitational wave emission from neutron star binaries can be used to discover any generic long-ranged muonic force due to the large inevitable abundance of muons inside neutron stars. [...]

A Standard Model explanation for the excess of electron-like events in MiniBooNE / Ioannisian, A. (Yerevan Phys. Inst. ; ITPM, Yerevan ; CERN)
We study the dependence of neutral current (NC) neutrino-induced $\pi^0$/photon production ($\nu_\mu + A \to \nu_\mu +1\pi^0 / \gamma + X$) on the atomic number of the target nucleus, A, at 4-momentum transfers relevant to the MiniBooNE experiment: $\Delta$ resonance mass region. [...]

Higgs transverse momentum with a jet veto: a double-differential resummation / Monni, Pier Francesco (CERN) ; Rottoli, Luca (Milan Bicocca U. ; INFN, Milan) ; Torrielli, Paolo (INFN, Turin ; Turin U.)
We consider the simultaneous measurement of the Higgs ($p_t^{\tiny{\mbox{H}}}$) and the leading jet ($p_t^{\tiny{\mbox{J}}}$) transverse momentum in hadronic Higgs-boson production, and perform the resummation of the large logarithmic corrections that originate in the limit $p_t^{\tiny{\mbox{H}}}\,,p_t^{\tiny{\mbox{J}}} \ll m_{\tiny{\mbox{H}}}$ up to next-to-next-to-leading-logarithmic order.

Spontaneous Conformal Symmetry Breaking in Fishnet CFT / Karananas, Georgios K. (Munich U., ASC) ; Kazakov, Vladimir (Ecole Normale Superieure, CNRS ; CERN) ; Shaposhnikov, Mikhail (ITPP, Lausanne)
