The scientific program of CHEP2015 will consist of plenary sessions with invited oral presentations, a number of parallel sessions comprising oral and poster presentations, and an industrial exhibition. The plenary sessions will occupy the four mornings and one afternoon (Thursday) and the parallel sessions will be held on Monday/Tuesday afternoons and in the morning of Thursday.

Contributions are solicited in the form of abstracts and the Program Committee, with the help of the International Advisory Committee, will use them to finalize the program.

Instructions for oral presenters

  • The timetable is now available! Please check by 30 March that you have Indico upload access, and tell us if you have any problem.
  • All the oral contributions in the parallel sessions will be in the form of 15 min. communications, including a brief discussion time. Please be prepared to present all material within 10-12 minutes so to allow for some question time.
  • Important: the final version of your slides should be uploaded to Indico by no later than 18:00 of the previous day of your talk. The Scientific Secretaries in each track will check the display of your slides (PDF/PowerPoint) using the PC and projector in the session room. Changes after that will not be reflected.
  • You cannot use your own PC for presentation. The PCs in the session rooms can play movies only in mpeg4 format.

Instructions for poster presenters

  • The timetable is now available! Please check by 30 March that you have Indico upload access, and tell us if you have any problem. You need to upload the PDF file of your poster, as well as bringing the printed poster itself. Please upload by no later than Sunday, 12 April (Japanese time).
  • Important: there is no facility to print posters in and around the conference site. Be sure to print your poster before coming to the conference and carry with yourself. The maximum allowed size of the poster is A0 (841mm x 1189mm, portrait). No space is available putting A0 poster in landscape orientation.
  • There are two poster sessions, A/B:
    Please check your poster allocation and booths map.
    • Session A: put up your poster by 13/April 10:30. The sessions are 13 April 13:30-14:00, 13/April 16:00-16:30, 14/April 13:30-14:00. Please remove your poster by 14/April 16:30.
    • Session B: put up your poster by 15/April 10:30. The sessions are 15 April 13:45-14:15, 16/April 10:30-11:00, 16/April 13:30-14:00. Please remove your poster by 16/April 16:00.
  • The participants will vote for posters, and selected ones will be allocated for oral presentations from 11:35 on 17/April (6 min/talk).
  • A selection of posters from each track will be displayed in front of the plenary session (the Auditorium) on 17/April. Be sure to bring them back with you.
