Ian P. J. Shipsey FRS (23 July 1959 – 7 October 2024) was a British experimental particle physicist who led many significant scientific collaborations associated with the CLEO, ATLAS, and CMS experiments, as well as being the head of the physics department at the University of Oxford between 2018 and 2024. He also helped discover the Higgs boson at CERN by development of a pixel detector that was used to detect it. [1]

Early life

Ian Shipsey was born on in Walthamstow, in East London, England on 23 July 1959. He graduated with a Bachelor of Science from Queen Mary University of London in 1982. [1] He went on to do a PhD in particle physics at the University of Edinburgh under the supervision of Ken J. Peach and Donald Cundy, graduating in 1986. His thesis focused on measuring the decay width of neutral K-mesons into two photons using data from the NA31 experiment carried out at the Super Proton Synchrotron at CERN. [2]

Career

After graduating from the University of Edinburgh, Shipsey went to Syracuse University for three years postodctoral research position. After this he was appointed assistant professor at Purdue University, later elevated to the Julian Schwinger distinguished professorship in 2007. He moved to the University of Oxford in 2013 as Henry Moseley Centenary Professor and became the head of the physics department in 2018. He was a fellow at St Catherine's College. [3]

During his time in the United States, he played a leading role in the CLEO experiment at Cornell University, being elected co-spokesperson three times. He constructed the muon detector and led studies into charmed baryon and bottom quark decay searches. Shipsey was one of the key proponents for and CLEO-c experiment, results from which were used to make the most precise tests for lattice QCD heavy quark calculations. [4]

From 2001 onwards he was working on the CMS experiment, constructing silicon cameras for the detector, using which he made the first cross section measurements of the Upsilon meson. With his students he also measured Upsilon meson suppression in Large Hadron Collider heavy-ion collisions provided experimental evidence for quark-gluon plasma. Shipsey also formed one of two teams that were the first to observe strange B meson di-muon decays. [5]

After arriving in Oxford, Shipsey became the Oxford ATLAS group leader where he oversaw the university's new silicon detector fabrication facility whose detector will be used for the high-luminosity LHC ATLAS upgrade. With his students he also managed to measure the Higgs mass and the Higgs decay width. Since 2008 he has been principal investigator for the Vera Rubin observatory at the Science and Technology Facilities Council, providing critical components for the observatory. [6] He has also worked on developing cameras for MAGIS in the United States and AION in the United Kingdom. [1]

He was elected as a Fellow of the Royal Society (FRS) in 2022 along with an honorary fellowship at the Institute of Physics in 2023. Additionally he also won the James Chadwick Medal and Prize in 2019. [7]

Personal life and death

Shipsey met Daniela Bortoletto at CERN during his PhD, with them getting married in 1988. They had one daughter together. In 1989, Shipsey contracted a sudden and near-fatal illness while at Cornell that left him totally deaf. [1] Twelve years later he acquired a cochlear ear implant that reinstated some of his hearing, following which he became a major advocate of the technology, giving over 100 public talks on it.

Shipsey died on 7 October 2024, at the age of 65. [8]

The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN in Switzerland and France. The goal of the CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.

<span class="mw-page-title-main">ATLAS experiment</span> CERN LHC experiment

ATLAS is the largest general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN in Switzerland. The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators. ATLAS was one of the two LHC experiments involved in the discovery of the Higgs boson in July 2012. It was also designed to search for evidence of theories of particle physics beyond the Standard Model.

<span class="mw-page-title-main">LHCb experiment</span> Experiment at the Large Hadron Collider

The LHCb experiment is a particle physics detector experiment collecting data at the Large Hadron Collider at CERN. LHCb is a specialized b-physics experiment, designed primarily to measure the parameters of CP violation in the interactions of b-hadrons. Such studies can help to explain the matter-antimatter asymmetry of the Universe. The detector is also able to perform measurements of production cross sections, exotic hadron spectroscopy, charm physics and electroweak physics in the forward region. The LHCb collaborators, who built, operate and analyse data from the experiment, are composed of approximately 1650 people from 98 scientific institutes, representing 22 countries. Vincenzo Vagnoni succeeded on July 1, 2023 as spokesperson for the collaboration from Chris Parkes. The experiment is located at point 8 on the LHC tunnel close to Ferney-Voltaire, France just over the border from Geneva. The (small) MoEDAL experiment shares the same cavern.

The DØ experiment stopped taking data in 2011, when the Tevatron shut down, but data analysis is still ongoing. The DØ detector is preserved in Fermilab's DØ Assembly Building as part of a historical exhibit for public tours.
