Towards the ultimate differential SMEFT analysis

Journal of High Energy Physics, 2020
We obtain SMEFT bounds using an approach that utilises the complete multi-dimensional differential information of a process. This approach is based on the fact that at a given EFT order, the full angular distribution in the most important electroweak ...

Anomaly detection using Unsupervised Machine Learning for Grid computing site operation [PDF]

EPJ Web of Conferences, 2020
A Grid computing site is composed of various services including Grid middleware, such as Computing Element and Storage Element. Text logs produced by the services provide useful information for understanding the status of the services.

Particle physics and cosmology [PDF]

General Relativity and Gravitation, 1995
ABSTRACTThe agreement between the observed light element abundances and calculations of homogeneous cosmological nucleosynthesis constrains inhomogenequs models, and suggests that most of the matter in the Universe is invisible Dark Matter. This could be in the form of neutrinos, lightest supersymmetric particles (LSPs) or axions.

Review of Particle Physics [PDF]

Physical Review D, 1996
This biennial review summarizes much of Particle Physics. Using data from previous editions, plus 1900 new measurements from 700 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric

Unified Experiment Monitoring [PDF]

EPJ Web of Conferences
The Unified Experiment Monitoring (UEM) is the project in WLCG with the objective to harmonize the WLCG job accounting reports across the LHC experiments, in order to provide aggregated reports of the compute capacity used by WLCG as a function of time ...

Solar neutrino probes of the muon anomalous magnetic moment in the gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$

Journal of High Energy Physics, 2020
Models of gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ can provide a solution to the long-standing discrepancy between the theoretical prediction for the muon anomalous magnetic moment and its measured value.

Cosmology and New Physics [PDF]

, 2006
A comparison of the standard models in particle physics and in cosmology demonstrates that they are not compatible, though both are well established. Basics of modern cosmology are briefly reviewed.

Study of the nonleptonic charmless $$B \rightarrow SS$$ B → S S decays with the QCD factorization approach

European Physical Journal C: Particles and Fields, 2023
Inspired by the brilliant prospects of the ongoing B meson experiments, the hadronic charmless B $${\rightarrow }$$ → SS decays are studied by considering the next-to-leading (NLO) contributions with the QCD factorization approach, where S denotes the ...

Baryogenesis and the New Cosmology [PDF]

, 2003
In this talk I begin with a brief review of the status of approaches to understanding the origin of the baryon asymmetry of the universe (BAU). I then describe a recent model unifying three seemingly-distict problems facing particle cosmology: the origin
