We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

Despite decades of attempts to reveal its flaws, the Standard Model of particle physics (SM)
has withstood all experimental tests and its predictions are in excellent agreement with data …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …

An inclusive search is presented for long-lived particles using displaced jets. The search
uses a data sample collected with the CMS detector at the CERN LHC in 2017 and 2018 …

We propose a type II seesaw model for light Dirac neutrinos to provide an explanation for the
recently reported anomaly in W boson mass by the CDF collaboration with 7σ statistical …

A bstract We study the capabilities of a muon collider experiment to detect disappearing
tracks originating when a heavy and electrically charged long-lived particle decays via X+→ …

These lectures provide an introduction to models and direct detection of dark matter. We
summarize the general features and motivations for candidates in the full dark matter mass …

Motivated by the recently reported anomaly in W boson mass by the CDF collaboration with
7σ statistical significance, we consider a singlet-doublet (SD) Majorana fermion dark matter …

We study an extension of the minimal gauged L μ-L τ model including three right-handed
singlet fermions and a scalar doublet to explain the anomalous magnetic moments of muon …

Abstract Feebly Interacting Massive Particles (FIMPs) are dark matter candidates that never
thermalize in the early universe and whose production takes place via decays and/or …
