Development of an "$α$-ToF" detector for correlated measurement of atomic masses and decay propertiesApr 24 2019We have developed a novel detector, referred to as an "$\alpha$-ToF detector", for correlated measurements of atomic masses and decay properties of low-yield, short-lived radioactive isotopes using a multi-reflection time-of-flight mass spectrograph. ...

Quantifying Correlated Truncation Errors in Effective Field TheoryApr 24 2019Effective field theories (EFTs) organize the description of complex systems into an infinite sequence of decreasing importance. Predictions are made with a finite number of terms, which induces a truncation error that is often left unquantified. We formalize ... More

1H(n,el) as a Cross Section Reference in a White Source Neutron Beam With the fissionTPCApr 23 2019We provide a quantitative description of a method to measure neutron-induced fission cross sections in ratio to elastic hydrogen scattering in a white-source neutron beam with the fission Time Projection Chamber. This detector has measured precision fission ... More

Comment on "Search for an axion-induced oscillating electric dipole moment for electrons using atomic magnetometers"Apr 23 2019In the recent work arXiv:1809.02446, the authors proposed a new method measuring the electron oscillating electric dipole moment (eOEDM) using atomic magnetomaters. This eOEDM is induced by the interaction between the electron magnetic dipole moment, ... More

Precise measurement of the mass difference and the binding energy of hypertriton and antihypertritonApr 23 2019Using the STAR (Solenoidal Tracker At RHIC) detector at the Relativistic Heavy Ion Collider (RHIC), we have measured the $\Lambda$ hyperon binding energy $B_\Lambda$ for the hypertriton, which is the lightest hypernucleus yet discovered and consists of ...

Disentangle contributions to small-system collectivity via scans of light nucleus-nucleus collisionsApr 23 2019The observation of multi-particle azimuthal correlations in high-energy small-system collisions has led to intense debate on its physical origin between two competing theoretical scenarios: one based on initial-state intrinsic momentum anisotropy (ISM), ...

Background Model of the CUPID-0 ExperimentApr 23 2019CUPID-0 is the first large mass array of enriched Zn$^{82}$Se scintillating low temperature calorimeters, operated at LNGS since 2017. During its first scientific runs, CUPID-0 collected an exposure of 9.95 kg yr. Thanks to the excellent rejection of ... More

Primordial non-Gaussianity in heavy-ion collisionsApr 23 2019We show that experimental data on cumulants of anisotropic flow in heavy-ion collisions probe the non-Gaussian statistics of the energy density field created right after the collision. We carry out a perturbative expansion of the initial anisotropies ... More

An alternative approach to populate and study the $^{229}$Th nuclear clock isomerApr 23 2019A new approach to observe the radiative decay of the $^{229}$Th nuclear isomer, and to determine its energy and radiative lifetime, is presented. Situated at a uniquely low excitation energy, this nuclear state might be a key ingredient for the development ... More
