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. A is defined by an effective Lagrangian describing interactions small number new particles. Simplified can equally well be described masses cross-sections. These...
We present the physics program of Belle II experiment, located on intensity frontier SuperKEKB $e^+e^-$ collider. collected its first collisions in 2018, and is expected to operate for next decade. It anticipated collect 50/ab collision data over lifetime. This book outcome a joint effort collaborators theorists through theory interface platform (B2TiP), an that commenced 2014. The aim B2TiP was elucidate potential impacts program, which includes wide scope topics: B physics, charm, tau,...
Abstract The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting the full scientific potential of CERN’s accelerator complex and infrastructures through projects complementary to LHC other possible future colliders. These will target fundamental physics questions in modern particle physics. This document presents status proposals presented framework Standard Model working group, explore their reach impact that CERN could have next 10–20 years on international landscape.

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...
Abstract This document presents the physics case and ancillary studies for proposed CODEX-b long-lived particle (LLP) detector, as well a smaller proof-of-concept demonstrator CODEX- $$\beta $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>β</mml:mi> </mml:math> , to be operated during Run 3 of LHC. Our development synthesizes ‘top-down’ ‘bottom-up’ theoretical approaches, providing detailed survey both minimal complete models featuring LLPs. Several these have not been...
We comprehensively study experimental constraints and prospects for a class of minimal hidden sector dark matter (DM) models, highlighting how the cosmological history these models informs signals. simple 'secluded' where DM freezes out into unstable mediator states, consider cosmic this sector, coupling to SM was sufficient keep two sectors in thermal equilibrium at early times. In well-motivated case mediators couple Standard Model (SM) via renormalizable interactions, requirement provides...
Adenovirus replication is controlled by the relocalization or modification of nuclear protein complexes, including promyelocytic leukemia (PML) domains and Mre11-Rad50-Nbs1 (MRN) DNA damage machinery. In this study, we demonstrated that E4 ORF3 effects both PML MRN proteins to similar structures within nucleus at early times after infection. These colocalize with ORF3. Through analysis specific viral mutants, found a direct correlation between reorganization infection establishment domains....
We study the minimal model of conformal technicolor, an SU(2) gauge theory near a strongly coupled fixed point, with symmetry softly broken by technifermion mass terms. Conformal breaking triggers chiral in pattern SU(4) → Sp(4), which gives rise to pseudo-Nambu-Goldstone boson that can act as composite Higgs boson. The top quark is elementary, and electroweak loop contributions are cut off entirely compositeness. In particular, requires no partners "little Higgs" mechanism. A nontrivial...
We argue that combining just a handful of searches for new physics at Run I the LHC is sufficient to exclude most supersymmetric extensions Standard Model in which gluino kinematically accessible and spectrum natural. Such models typically give rise significant MET, top quarks and/or high object multiplicity, we show having even one these signatures generally results stringent limits. also identify, among lack signatures, few gaps coverage remaining, propose search strategies close gaps. Our...
This report summarizes the work of Energy Frontier Top Quark working group 2013 Community Summer Study (Snowmass).
West Nile virus (WNV) is a human pathogen that can cause symptomatic infections associated with meningitis and encephalitis. Previously, we demonstrated replication of WNV inhibits the interferon (IFN) signal transduction pathway by preventing accumulation phosphorylated Janus kinase 1 (JAK1) tyrosine 2 (Tyk2) (J. T. Guo et al., J. Virol. 79:1343-1350, 2005). Through genetic analysis, have now identified determinant on nonstructural protein 4B (NS4B) controls IFN resistance in HeLa cells...
A hidden sector containing light long-lived particles provides a well-motivated place to find new physics. The recently proposed MATHUSLA experiment has the potential be extremely sensitive originating from rare meson decays in very long lifetime region. In this work, we illustrate strength with specific example of scalar mixed standard model-like Higgs boson, model where can further probe unexplored parameter space exotic decays. Design augmentations should considered order maximize ability...
As the majority of LHC searches are focused on prompt signatures, specific long-lived particles have potential to be overlooked by otherwise systematic new physics programs at ATLAS and CMS. While in many cases superparticles now stringently constrained existing exotic searches, we point out that highly motivated model gauge mediation with staus as next-to-lightest superparticle (NLSP) has received less attention. We recast for heavy stable charged particles, disappearing tracks,...
The early COVID-19 pandemic was characterized by rapid global spread. In Maryland and Washington, DC, United States, more than 2500 cases were reported within 3 weeks of the first detection in March 2020. We aimed to use genomic sequencing understand initial spread SARS-CoV-2 — virus that causes region. analyzed 620 samples collected from Johns Hopkins Health System during 11–31, 2020, comprising 28.6% total DC. From these samples, we generated 114 complete viral genomes. Analysis genomes...
Adenovirus early proteins E4 ORF3 and ORF6 have complementary functions during viral infection. Both facilitate efficient DNA replication, late protein expression, prevention of concatenation genomes. Additionally, is involved in the shutoff host cell synthesis through its interaction with E1B 55K protein. This complex also leads to degradation p53. A unique function reorganization nuclear structures known as PML oncogenic domains (PODs). The these unclear, but PODs been implicated a number...
