Sergei V. Chekanov (born 1969 in Minsk, Soviet_Union then Belarus ) is a Belarussian-American particle and experimental physicist. He is also a computational scientist who published several books on computations and data analysis . He obtained his master degree in theoretical physics in 1992 from the Belarusian State University (Minsk, Belarus ) and entered a Ph.D. position at the Academy of Science of Belarus. His main Ph.D. topic was the theory of Quantum chromodynamics (1992-1995). Then he switched to a Ph.D. in experimental particle physics. He holds a Ph.D in experimental particle physics from the Radboud University Nijmegen, The Netherlands (1998). As a particle physicist, he worked at DESY laboratory (Hamburg, Germany), CERN laboratory (Geneva, Switzerland) and at Argonne National Laboratory (USA).

Professional activity

Currently S.Chekanov works in the field of particle physics at Argonne National Laboratory. He was a member of the L3 experiment/ CERN, ZEUS experiment / DESY and ATLAS experiment / CERN international experiments. His preferred physics areas of interest include QCD data analysis, physics beyond the Standard Model, physics performance of future HEP experiments, and design of software for current and future experiments. According his publication records in ORCID , he co-authored about 200 professional papers (most of them are published in peer-reviewed journals) and other articles, including a dozen of experimental papers from large-scale particle-colliding experiments. He contributed to physics results described in more in several thousand publications of international particle collider experiments.

Among major physics highlights, he was a primary author of highest-precision F2cc measurements used to understand charm structure of the proton, evidence for strange pentaquarks (not confirmed) in ep, a first observation of the strange sea at HERA, a first observation of direct (anti) deuterons in ep, a first observation and measurements of photons above the TeV (teraelectronvolt) energy and led many high-precision QCD measurements in e+e-/ep/pp collisions that establish the Standard Model. His current work is focused on searches for new physics beyond the Standard Model at the LHC.

In 2022 - 2023, he led a group of scientists at the LHC to publish a first article in particle physics where the entire collision events from the LHC collider were converted into "replicas" with the help of a deep neural network (autoencoder), and then searches for new physics phenomena were performed on replicas with large reconstruction losses. This method of using unsupervised machine learning trained on actual data, using the entire collision kinematics in the form of RMM objects without Monte Carlo simulations, has been conceptualized by him in several publications during 2019-2022, see the references [40]-[41] of the paper . This style of machine learning technique for anomaly detection offers a new paradigm for searching for new-physics phenomena in particle physics.

Software for particle physics

He led and implemented several large-scale software projects for high-energy particle physics, such as HepSim Monte Carlo repository for collision events, Jas4pp analysis framework for particle physics and other software packages. He took several leadership roles, such as ATLAS experiment event display coordinator (2019-2021), QCD physics coordinator (2003-2018, ZEUS/HERA experiment), ATLAS upgrade calorimeter simulation coordinator (2016-2018) and other.

Public activity

As a software designer, he was a primary developer of DataMelt scientific program (original name JHepWork (2005),SCaViS) for numeric and statistical computations and several other scientific computing projects available from SourceForge.

As a book author on scientific computing, he wrote two books on numerical and statistical computations based on Java and Jython programming languages. The books have been published by Springer-Verlag (2010) and Springer International (2016) . The main focus of the books is scientific computing using Java programming language and the usage of Java scripting languages. According to the Springer International, the latter book was top 25% most downloadable books in 2016 and 2017 in the category "Advanced Information and Knowledge Processing". Since the publication of the book, Springer has detected 34k downloads until April 2019. He is also known for promoting open-source scientific computing for science and education as a founder of the jWork.ORG community portal .

S.Chekanov is a founder, primary designer and maintainer of the HandWiki encyclopedia (launched in Oct 2019) on computing, science, technology and general knowledge. This encyclopedia uses an alternative publication policy compared to what is used in Wikipedia. HandWiki is the #3 world's largest wiki in terms page counts. It has a larger number of articles than in  Wikipedia for more than 10,000 categories dedicated to science and technology. HandWiki is non-for-profit and non-commercial.

In 2020, he joined to the Knowledge Standards Foundation (KSF) team founded by Wikipedia ex-founder Larry Sanger. As a member of the KSF, he started to explore the technical design and software implementations of the Encyclosphere which is expected to unite all world's online encyclopedias . In May 2021, he created a new file format for storing encyclopedic content of wikis and online encyclopedias in general (ZWI file format). In Jan. 2021, he co-authored the FactSeek search tool and then, in 2022, he launched the Encyclone search engine for searches in world's encyclopedias. In Oct. 2021, he designed and programmed EncycloReader that combines a search engine for online encyclopedias with a reader that applies a common standard to view encyclopedic articles.

In July 2024, S. Chekanov published a book titled "The Designed World of Information: Unveiling the Incredible Realm Beyond" . This work explores the concept of synchronicity, first introduced by Carl Jung, and proposes a method for estimating the probability that synchronicity arises from pure chance and randomness. Chekanov applies this new technique to assess the likelihood of synchronicity in various historical coincidences. By demonstrating that the role of chance in these phenomena is improbable, he connects synchronicity to questions about the origin of the universe, biological evolution, quantum mechanics, elementary particles, and the remarkable beauty of natural laws. The book concludes that the synchronicity effect can be seen as evidence for the existence of God, although it does not dismiss the simulation theory. Where science falls short of providing definitive answers, this book offers insights that illuminate our consciousness and its relationship with the informational reality shaping the events and processes of our world. The original text is also available in Russian.
