Evaluation of a high-performance storage buffer with 3D XPoint devices for the DUNE data acquisition system [PDF]

EPJ Web of Conferences, 2021
The DUNE detector is a neutrino physics experiment that is expected to take data starting from 2028. The data acquisition (DAQ) system of the experiment is designed to sustain several TB/s of incoming data which will be temporarily buffered while being ...

A new approach to color-coherent parton evolution

Journal of High Energy Physics, 2023
We present a simple parton-shower model that replaces the explicit angular ordering of the coherent branching formalism with a differentially accurate simulation of soft-gluon radiation by means of a non-trivial dependence of the splitting functions on ...

A new picture of quantum tunneling in the real-time path integral from Lefschetz thimble calculations

Journal of High Energy Physics, 2023
It is well known that quantum tunneling can be described by instantons in the imaginary-time path integral formalism. However, its description in the real-time path integral formalism has been elusive. Here we establish a statement that quantum tunneling

Backpropagating Hybrid Monte Carlo algorithm for fast Lefschetz thimble calculations

Journal of High Energy Physics, 2022
The Picard-Lefschetz theory has been attracting much attention as a tool to evaluate a multi-variable integral with a complex weight, which appears in various important problems in theoretical physics.

Tensor renormalization group and the volume independence in 2D U(N) and SU(N) gauge theories

Journal of High Energy Physics, 2021
The tensor renormalization group method is a promising approach to lattice field theories, which is free from the sign problem unlike standard Monte Carlo methods.

Data-driven modeling of beam loss in the LHC

Frontiers in Physics, 2023
In the Large Hadron Collider, the beam losses are continuously measured for machine protection. By design, most of the particle losses occur in the collimation system, where the particles with high oscilla-tion amplitudes or large momentum error are ...

Confronting dark fermion with a doubly charged Higgs in the left–right symmetric model

European Physical Journal C: Particles and Fields, 2022
We consider a fermionic dark matter (DM) in the left–right symmetric framework by introducing a pair of vector-like (VL) doublets in the particle spectrum. The stability of the DM is ensured through an unbroken $$\mathcal {Z}_2$$ Z 2 symmetry. We explore

Search for a compressed supersymmetric spectrum with a light gravitino

Journal of High Energy Physics, 2017
Presence of the light gravitino as dark matter candidate in a supersymmetric (SUSY) model opens up interesting collider signatures consisting of one or more hard photons together with multiple jets and missing transverse energy from the cascade decay. We
