This document proposes a collection of simplified models relevant to the design new-physics searches at LHC and characterization their results. Both ATLAS CMS have already presented some results in terms models, we encourage them continue expand this effort, which supplements both signature-based benchmark model interpretations.

In recent years, advanced threat attacks are increasing, but the traditional network intrusion detection system based on feature filtering has some drawbacks which make it difficult to find new in time.

A number of mobility models have been proposed for the purpose either analyzing or simulating movement users in a mobile wireless network. Two more popular are random waypoint and direction models. The model is physically appealing but difficult to understand. Although less physically, it much easier User speeds easily calculated, unlike model, and, as we observe, user positions directions uniformly distributed. contribution this paper establish last property rich class that allow future...

We examine the theoretical motivations for long-lived particle (LLP) signals at LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are common prediction wide range theories that address unsolved fundamental mysteries such as naturalness, dark matter, baryogenesis and neutrino masses, represent natural generic possibility physics beyond SM (BSM). In most cases LLP lifetime can be treated free parameter from $\mu$m scale up to Big Bang Nucleosynthesis limit $\sim 10^7$m....
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at weak scale. When produced experiments such as Large Hadron Collider (LHC) CERN, these long-lived (LLPs) decay far from interaction vertex of primary proton-proton collision. Such LLP signatures distinct those promptly decaying targeted by majority searches for new physics LHC, often requiring customized techniques identify, example, significantly displaced vertices, tracks with...

Neural networks are a powerful class of nonlinear functions that can be trained end-to-end on various applications. While the over-parametrization nature in many neural renders ability to fit complex and strong representation power handle challenging tasks, it also leads highly correlated neurons hurt generalization incur unnecessary computation cost. As result, how regularize network avoid undesired redundancy becomes an important issue. To this end, we draw inspiration from well-known...
The QCD axion provides an elegant solution to the Strong CP Problem. While minimal realization is vulnerable so-called "Axion Quality Problem", we will consider a more robust in presence of mirror sector related Standard Model by (softly broken) $\mathbb{Z}_2$ symmetry. We point out that resulting "heavy" axion, while satisfying all theoretical and observational constraints, has large uncharted parameter space which allows it be probed at LHC as Long-Lived Particle (LLP). small defining...
