NEW: Deadlines for application for the poster session and for financial support have been extended to 15 May 2003.

The XXI International Symposium on Lepton and Photon Interactions at High Energies (Lepton Photon 2003) will be held at the Fermi National Accelerator Laboratory in Batavia, Illinois. The Symposium will begin on Monday 11 August 2003 and conclude Saturday 16 August 2003, with a break on Wednesday. Presentations will be in Fermilab's Ramsey Auditorium.

Lepton Photon 2003 is sponsored by the International Union of Pure and Applied Physics (IUPAP), the U.S. Department of Energy, the U.S. National Science Foundation, and Fermilab. Other contributors include the National Aeronautics and Space Administration and Itech, Okinawa.

Participation in the Symposium is by invitation only. Invitations will be extended to scientists nominated by the IUPAP Country Coordinators.

The Symposium will consist of plenary talks reviewing the current state of heavy quark physics, neutrinos, electroweak physics, proton structure, QCD and new particle searches. New theoretical developments will be reviewed and one session will be dedicated to particle-astrophysics and cosmology. Friday afternoon will be devoted to tours of the Fermilab site and to a poster session featuring the activities of particle physics laboratories throughout the world.

Papers relevant to the scientific program may be submitted to the Symposium by following instructions on our website at Paper submission will start on 3 March 2003. The authors, titles, abstracts, and links to the papers will be available on the Lepton Photon 2003 web site. The list of accepted papers (but not the papers themselves) will be included in the Proceedings. Papers should be submitted by 15 July 2003 so invited speakers may review them before the Symposium. Papers will be publicly available as soon as they are submitted. Authors who wish to keep results confidential until the Symposium may communicate privately with the appropriate invited speaker and delay submission until 8 August 2003.

Copies of all presentations will be accessible via the Symposium website at the conclusion of the Symposium. Written proceedings of the Symposium will be published.

In order to encourage participation by younger physicists, there will be a poster session with additional Symposium invitations reserved for the poster presenters. Applications for the poster session should consist of a one-page vitae and abstract. Please send poster applications to The deadline is 15 May 2003. Posters prepared by participants will be on display at the beginning of the Symposium, Monday - Wednesday 11 - 13 August 2003. A list of accepted posters will appear in the Proceedings.

The Symposium will also feature invited posters from particle physics laboratories. These posters will be on display in the Wilson Hall Atrium during the Friday afternoon poster session.

A limited amount of financial support will be available for early-career physicists and for individuals from developing countries. Both partial and full stipends will be awarded. Participants interested in applying for financial support should send the following material to

a) A one-page vitae including institutional affiliation, address, phone number, fax number, e-mail address, and a summary of education and experience.
b) A short letter describing benefit to the candidate of this symposium. The applicant should describe the level of support required.
c) A brief letter of recommendation from a supervising professor or senior scientist.

The deadline for receipt of the material is 15 May 2003.

All invitees are asked to register beginning 3 March 2003. Please register electronically, if possible, via our website at If you are unable to register electronically, the registration form may be printed and faxed to 630-840-8589, or mailed to the Symposium Secretariat (address below).

The registration fee for the Symposium is $400, payable in U. S. dollars only, and if paid before 30 May 2003. After 30 May 2003, the registration fee will increase to $450.

Blocks of rooms have been reserved at five hotels in Naperville, Illinois:

  • Hilton Lisle/Naperville Hotel
  • Holiday Inn Select Naperville Hotel
  • Best Western Naperville Inn - This hotel is now full.
  • Exel Inn
  • Days Inn

These hotels will be serviced by a Symposium bus service in the mornings and evenings of the days the Symposium is in session. All of these hotels are located approximately 13 km (8 miles) from Fermilab, conveniently adjacent to I-88/East-West Tollway at the Naperville Road exit. The hotel locations offer easy access by car to Fermilab as well as O'Hare International Airport, Midway Airport, and Downtown Chicago.

Reservations must be made directly with the hotels. Please see the Lepton Photon 2003 Travel/hotel web page for more details.

Participants will be responsible for meal costs. Some of the hotels offer continental breakfasts or coffee as part of the room fee. Others have restaurants in the hotels. Please see the Lepton Photon 2003 Travel/hotel web page for more information. You may also take the early shuttle bus and have breakfast at Fermilab in the Eurest Dining Center. Dinners may be obtained at the hotel restaurants or at local area restaurants. A listing of local restaurants will be provided in the registration packet.

During the Symposium, lunches will be available for purchase in the Eurest Dining Center in Wilson Hall, at the "Food Tent" in front of Wilson Hall, or at local area restaurants. Details of these arrangements will be posted at a later date.

Transportation to and from Chicago O'Hare Airport and Midway Airport is available by limousine, car rental, or taxi. Although the Symposium will be providing shuttle-bus service to and from Fermilab to the Symposium hotels, there is no public transportation to Fermilab and taxi service is costly. So, if you plan to go out in the evenings to restaurants or other evening events that are not serviced by your hotel's local area shuttle, you are encouraged to rent a car, sharing where convenient.

Shuttle buses will be making regularly scheduled pickups at the various Symposium hotels in the morning and return trips to the Symposium hotels at the end of each day's events. This shuttle-bus service will start on Monday morning, 11 August 2003.

Parking near Wilson Hall is limited and restricted. If you are not taking the Symposium shuttle and wish to drive to Fermilab, overflow parking is being planned in several areas near Wilson Hall but some walking will be involved.

Please see the Lepton Photon 2003 Travel/hotel web page for more information.

Fermilab is located on 27.5 km2 of what used to be Illinois farmland, approximately 60 km from Chicago, conveniently located near both O'Hare and Midway airports. Fermilab's prairies, forests, ponds, and wetlands are home to a large variety of birds, fish, butterflies, and even a herd of buffalo - as well as particle physics research.

The weather in Chicago is well known for its strong seasonal changes. Summers can be very hot and humid with temperatures reaching as high as 35 degrees Celsius (100 degrees Fahrenheit). Wind and humidity, however, will influence the way your body feels the temperature. Rain is possible during the time of the Symposium.

In summer, many buildings are cooled by air-conditioning. A light sweater or jacket is recommended for wearing when inside. While spending time outside, protect yourself from getting sunburned.
