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 four candidate events in the signal region of $K_L\to \pi^0 \nu\bar\nu$ search, where the standard model only expects $0.10\pm 0.02$ 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. [...]

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.

This review describes the duality between color and kinematics and its applications, with the aim of gaining a deeper understanding of the perturbative structure of gauge and gravity theories. [...]

Spontaneous Conformal Symmetry Breaking in Fishnet CFT / Karananas, Georgios K. (Munich U., ASC) ; Kazakov, Vladimir (Ecole Normale Superieure, CNRS ; CERN) ; Shaposhnikov, Mikhail (ITPP, Lausanne)
Quantum field theories with exact but spontaneously broken conformal invariance have an intriguing feature: the vacuum energy (cosmological constant) in them is equal to zero. [...]

A lower bound on the primordial black hole merger rate / Vaskonen, Ville (King's Coll. London ; NICPB, Tallinn) ; Veermäe, Hardi (NICPB, Tallinn ; CERN)
We derive a lower bound on the merger rate of primordial black hole (PBH) binaries by estimating the maximal fraction of binaries that were perturbed between formation in the early universe and merger, and computing a conservative merger rate of perturbed binaries. [...]
