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. [...]

New physics implications of recent search for $K_L \to \pi^0 \nu\bar{\nu}$ at KOTO / Kitahara, Teppei (Technion ; KMI, Nagoya ; Nagoya U., IAR) ; Okui, Takemichi (Florida State U. ; KEK, Tsukuba) ; Perez, Gilad (Weizmann Inst.) ; Soreq, Yotam (Technion ; CERN) ; Tobioka, Kohsaku (Florida State U. ; KEK, Tsukuba)
The KOTO experiment recently reported three candidate events in the signal region of $K_L\to \pi^0 \nu\bar\nu$ search, where the standard model only expects $0.05\pm 0.02$ events. [...]

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. [...]

Consistency checks for two-body finite-volume matrix elements: I. Conserved currents and bound states / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Jackura, Andrew W. (Jefferson Lab ; Old Dominion U.)
Recently, a framework has been developed to study form factors of two-hadron states probed by an external current. [...]

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.

Second-order QCD corrections to event shape distributions in deep inelastic scattering / Gehrmann, T. (Zurich U.) ; Huss, A. (CERN) ; Mo, J. (Zurich U.) ; Niehues, J. (Durham U., IPPP)
We compute the next-to-next-to-leading order (NNLO) QCD corrections to event shape distributions and their mean values in deep inelastic lepton-nucleon scattering. [...]

Correlating $\epsilon^\prime/\epsilon$ to hadronic $B$ decays via $U(2)^3$ flavour symmetry / Crivellin, Andreas (PSI, Villigen ; Zurich U.) ; Gross, Christian (INFN, Pisa ; Pisa U. ; CERN) ; Pokorski, Stefan (Warsaw U.) ; Vernazza, Leonardo (Nikhef, Amsterdam)
There are strong similarities between charge-parity (CP) violating observables in hadronic $B$ decays (in particular $\Delta A^-_{\rm CP}$ in $B\to K\pi$) and direct CP violation in Kaon decays ($\epsilon^\prime$): All these observables are very sensitive to new physics (NP) which is at the same time CP and isospin violating (i.e. [...]
