Sookyung Choi is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sookyung Choi rather than just read about it. In short: SooKyung Choi is a South Korean particle physicist at Gyeongsang National University. She is part of the Belle experiment and was the first to observe the X(3872) meson in 2003.

Key takeaways

Sookyung Choi belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sookyung Choi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sookyung Choi from memory before moving on to harder problems.

Reference excerpt

SooKyung Choi is a South Korean particle physicist at Gyeongsang National University. She is part of the Belle experiment and was the first to observe the X(3872) meson in 2003. She won the 2017 Ho-Am Prize in Science.

Early life and education Choi studied physics at the Kyungpook National University, graduating in 1979 with a Bachelor's degree and 1993 with a PhD. Her supervisors were Dongchul Son and C. Joo. After graduating, Choi joined Seoul National University, working on Møller and Bhabha scattering. She was appointed Professor at Gyeongsang National University, where she worked with the High Energy Accelerator Research Organization (KEK).

Career Choi's work mainly concerns CP violation and decays of the B meson. Choi worked on the Belle experiment, where she identified several new types of fundamental particles. The first results from Belle came in 2002, finding large cross-sections for the e+e−continuum. In 2003 she discovered the X(3872) meson; a new kind of heavy particle, which does not fit the quantum model as it was made up of four quarks. Choi predicted the X(3872) particle could be a charmonium state or a DD* hadronic molecule. The work was confirmed by a team at the Fermi National Accelerator Laboratory. Choi went on to discover the Y(3940), the Zc(3900) and Z(4430) particles, which proved that particles can exist in a range of forms. Choi studied the decays of these extensively. She was involved with the study of other charmonium states; using the ϒ(4S) and ϒ(5S) resonances at the Belle detector. Choi has collaborated with the BES III experiment, which studied center of mass energies between 2.9 and 4.42 GeV. The BES III experiment identified new charmonium states with non-zero electric charge. CP violation was first confirmed at the Belle experiment and would go on to win the 2008 Nobel Prize in Physics. The experiments stopped operation in June 2010. Choi is part of the Belle II experiment, which collected their first collisions in 2018. She served on the advisory board of the International Conference on High Energy Physics in Seoul in July 2018.

Awards and honors In 2004, Choi was awarded the Scientist of the Month award by the Ministry of Science and ICT and National Research Foundation of Korea. In 2017, Choi won the Ho-Am Prize in Science. The following year, Choi became a laureate of the Asian Scientist 100 by the Asian Scientist.

Worked examples

Example 1 — a first encounter with Sookyung Choi

Start with the simplest possible case. Write down what Sookyung Choi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sookyung Choi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sookyung Choi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sookyung Choi

In research: Sookyung Choi appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sookyung Choi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sookyung Choi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century South Korean women scientists, Academic staff of Seoul National University, Kyungpook National University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Sookyung Choi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
