Many physics goals of future large LAr detectors like DUNE hinge on the achievement of high radio-purity to minimize backgrounds to low-energy signals like supernova and solar neutrinos. Radon in particular is a concerning source of backgrounds, as its progeny generate diffuse signals from betas, gammas, and neutrons at the MeV-scale. In this talk, we report measured limits on the specific...
A revolution in networking is changing how we compute, but we lack the tools that can channel this new capability to benefit science. It is now possible to write programs that operate "in" the network---on network cards (NICs) and network switches themselves, rather than on servers. These programs can analyze and reduce huge volumes of data as they flow through the network---at higher...
NOvA is a long-baseline accelerator-based neutrino experiment based in the US. NOvA uses an intense neutrino beam produced at Fermilab’s accelerator complex to make physics measurements of neutrino oscillations, neutrino cross sections, and much more. For its physics goals, NOvA uses two functionally-identical detectors. The Near Detector (ND) is situated at Fermilab, 1 km from the neutrino...
The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino experiment that will send an intense beam of neutrinos through two particle detectors; a near detector located at Fermilab (Chicago) and far detector located at ~1.5 km underground and ~1300km from the near detector at Sanford Underground Research Facility (SURF) in South Dakota.
The DUNE far detector will be...
We study the Higgs production process at a muon collider using b-pair decays of the Higgs bosons. Efficient identification and good measurement resolution for the b-jet pair invariant mass are crucial for unearthing the Higgs signal. However, the beam-induced background has potential to drastically degrade the performance. We report on the full simulation studies of the degradation of the...
The Short Baseline Near Detector (SBND), a 112 ton liquid argon time projection chamber (LArTPC), is the near detector of the Short Baseline Neutrino Program at Fermilab. In a LArTPC, ionization electrons from a charged particle track drift along the electric field lines, inducing bipolar signals on the induction planes, and a unipolar signal collected on the collection plane. In this talk, we...
Electron-positron pair production and hadron photoproduction are the most critical beam-induced backgrounds at linear electron-positron colliders. Predicting them accurately governs the design and optimization of detectors at these machines and, ultimately, their physics reach. With the proposal, adoption, and first specification of the C$^3$ collider concept, it is of primary importance to...
Many Beyond the Standard Model (BSM) ideas envisage a connection between the Dark Matter (DM) and Baryonic matter densities (i.e. from Standard Model (SM)) where the DM has an asymmetry in the ratio of matter over antimatter similar to baryons. The dark sector is connected to the visible sector by a heavy mediator. It is highly relevant to explore the signature of this connection as part of...
