This paper describes the operation of Coherent CAPTAIN-Mills (CCM) detector located at Los Alamos Neutron Science Center National Laboratory. CCM is a 10-ton liquid argon 20 meters from high flux neutron/neutrino source and designed to search for sterile neutrinos (${\ensuremath{\nu}}_{s}$'s) light dark matter (LDM). An engineering run was performed in fall 2019 study characteristics CCM120 by searching coherent scattering signals consistent with ${\ensuremath{\nu}}_{s}$'s LDM resulting...
The proposed Electron-Ion Collider (EIC) will utilize high- luminosity high-energy electron+proton ( e + p ) and electron+nucleus A collisions to solve several fundamental questions including searching for gluon saturation studying the proton/nuclear structure. Complementary ongoing EIC project detector technical prototype carried out by ePIC collaboration, a Depleted Monolithic Active Pixel Sensor (i.e., MALTA2) based fast timing silicon tracking (FMT) has been provide additional hits track...
In Aguilar-Arevalo [], we explored various effective field theories that could explain the MiniBooNE excess involving long-lived particles produced from charged meson decays and sensitivity of Coherent CAPTAIN Mills experiment to these models. this addendum, extend analysis project upcoming MicroBooNE data particle models considered in previous work. We find a dedicated single photon final state with longer exposure improved signal efficiency will be sensitive new physics explanations...
We report the first results of a search for leptophobic dark matter (DM) from Coherent-CAPTAIN-Mills (CCM) liquid argon (LAr) detector. An engineering run with 120 photomultiplier tubes (PMTs) and 17.9×10^{20} protons on target (POT) was performed in fall 2019 to study characteristics CCM The operation this 10-ton detector strictly light based threshold 50 keV used coherent elastic scattering off nuclei detect DM. Despite only 1.5 months accumulated luminosity, contaminated LAr, nonoptimized...
We show results from the Coherent CAPTAIN Mills (CCM) 2019 engineering run which begin to constrain regions of parameter space for axion-like particles (ALPs) produced in electromagnetic particle showers an 800 MeV proton beam dump, and further investigate sensitivity ongoing data-taking campaigns CCM200 upgraded detector. Based on beam-on background estimates run, we make realistic extrapolations reduction based expected shielding improvements, reduced width, analysis-based techniques...
A solution to the MiniBooNE excess invoking rare three-body decays of charged pions and kaons new states in MeV mass scale was recently proposed as a dark-sector explanation. This class illuminates fact that, while were focused target-mode run, their decay products isotropically suppressed beam-dump-mode run which no observed. suggests physics correlated mesonic sector. We investigate an extended set phenomenological models that can explain dark sector solution, utilizing long-lived...
Abstract A key aspect of the LHC Injectors Upgrade project is connection PSB to newly built Linac4 and related installation a new 160 MeV charge-exchange injection system. The system was commissioned in winter 2020/21 now used operationally tailor transverse characteristics for various beam types at CERN, such as high-intensity fixed target beams, single bunch high-brightness beams LHC. This contribution outlines different strategies producing discusses application numerical optimization...

The art of capturing an image through improvised pinhole device traces back to ancient China and Greece the Renaissance reaching its height popularity in 1880s. era modern sharp-focus lens camera marked end photography as a major form. Three decades ago Eric Renner resuscitated form with his publication Pinhole Journal that ushered resurgence interest by artists seeking alternative often conceptual vision photography. Nancy Spencer have out this effort built world's most collection from 31...
The proposed high-luminosity high-energy Electron-Ion Collider (EIC) will provide a clean environment to precisely study several fundamental questions in the fields of and nuclear physics . A low material budget high granularity silicon vertex/tracking detector is critical carry out series hadron jet measurements at future EIC especially for heavy flavor product reconstruction or tagging. conceptual design forward tracking with pseudorapidity coverage from 1.2 3.5 has been developed...
The future Electron-Ion Collider (EIC) will utilize a series of high-luminosity high-energy electron+proton ($e+p$) and electron+nucleus ($e+A$) collisions to explore the inner structure nucleon nucleus matter formation process. Heavy flavor hadron jet measurements at EIC play an essential role in determining nucleon/nucleus parton distribution function heavy quark hadronization process not well constrained kinematic regions.
