Production and optical properties of liquid scintillator for the JSNS$^{2}$ experimentJun 01 2019The JSNS$^{2}$ (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) experiment is to search sterile neutrino with 24 m short baseline at J-PARC. The JSNS$^{2}$ detector will be filled with 17 mass tons of Gadolinium loaded liquid scintillator ... More
Search for $Ω(2012)\to KΞ(1530) \to KπΞ$ at BelleJun 01 2019Using data samples of $e^+e^-$ collisions collected at the $\Upsilon(1S)$, $\Upsilon(2S)$, and $\Upsilon(3S)$ resonances with the Belle detector, we search for the three-body decay of the $\Omega(2012)$ baryon to $K\pi\Xi$. This decay is predicted to ... More
Dark matter search in missing energy events with NA64Jun 01 2019Jun 06 2019A search for sub-GeV dark matter production mediated by a new vector boson $A'$, called dark photon, is performed by the NA64 experiment in missing energy events from 100 GeV electron interactions in an active beam dump at the CERN SPS. From the analysis ... More
Constraint of the MINERvA Medium Energy Neutrino Flux using Neutrino-Electron Elastic ScatteringMay 31 2019Elastic neutrino scattering on electrons is a precisely-known purely leptonic process that provides a standard candle for measuring neutrino flux in conventional neutrino beams. Using a total sample of 810 neutino-electron scatters after background subtraction, ... More
Combination of CMS searches for heavy resonances decaying to pairs of bosons or leptonsMay 31 2019A statistical combination of searches for heavy resonances decaying to pairs of bosons or leptons is presented. The data correspond to an integrated luminosity of 35.9 fb$^{-1}$ collected during 2016 by the CMS experiment at the LHC in proton-proton collisions ... More
Where Are We With Light Sterile Neutrinos?May 31 2019We review the status of searches for sterile neutrinos in the $\sim 1$ eV range, with an emphasis on the latest results from short baseline oscillation experiments and how they fit within sterile neutrino oscillation models. We present global fit results ... More
Detecting Dark Matter with Aharonov-BohmMay 31 2019While the evidence for dark matter continues to grow, the nature of the dark matter remains a mystery. A dark $U(1)_D$ gauge theory can have a small kinetic mixing with the visible photon which provides a portal to the dark sector. Magnetic monopoles ... More
Direct Detection of Light Dark Matter with MagnonsMay 31 2019Scattering of light dark matter with sub-eV energy deposition can be detected with collective excitations in condensed matter systems. When dark matter has spin-independent couplings to atoms or ions, it has been shown to efficiently excite phonons. Here ... More
Fiducial cross sections for the four-lepton decay mode in Higgs-plus-jet production up to NNLO QCDMay 31 2019The four-lepton decay mode of the Higgs boson allows for a clean kinematic reconstruction, thereby enabling precision studies of the Higgs boson properties and of its production dynamics. We compute the NNLO QCD corrections to fiducial cross sections ... More
Properties of $Z_c^{\pm}(3900)$ produced in $p \bar p$ collisionMay 31 2019We study the production of the exotic charged charmonium-like state $Z_c^{\pm}(3900)$ in $p \bar p$ collisions through the sequential process $\psi(4260) \rightarrow Z_c^{\pm}(3900) \pi^{\mp}$, $Z_c^{\pm}(3900) \rightarrow J/\psi \pi^{\pm}$. Using the ... More
Radiogenic backgrounds in the NEXT double beta decay experimentMay 31 2019Natural radioactivity represents one of the main backgrounds in the search for neutrinoless double beta decay. Within the NEXT physics program, the radioactivity-induced backgrounds are measured with the NEXT-White detector. Data from 37.9 days of low-background ... More
Scattering studies with low-energy kaon-proton femtoscopy in proton-proton collisions at the LHCMay 31 2019The study of the strength and behaviour of the antikaon-nucleon ($\mathrm{\overline{K}N}$) interaction constitutes one of the key focuses of the strangeness sector in low-energy Quantum Chromodynamics (QCD). In this letter a unique high-precision measurement ... More
Impact on the decay rate of $B_s\to μ^+μ^-$ from the dispersive two-photon transitionMay 31 2019We study the long-distance contribution to $B_s\to\mu^+\mu^-$ decay, which is generated by the two-photon intermediate state via $B_s\to\gamma^*\gamma^*\to\mu^+\mu^-$ transition. It is found that the dispersive two-photon amplitude can interfere with ... More
