Second circular
    KEK theory center workshop on
    Hadron physics with high-momentum hadron beams at J-PARC in 2015
    March 13-16, 2015
    Kobayashi Hall, 1st Floor, Kenkyu-Honkan, KEK, Tsukuba, Japan

***** Pre-workshop meeting: March 12, 2015 *****
"Toward a proposal on high-energy hadron physics at J-PARC"
Meeting Room 1, 1st Floor, Kenkyu-Honkan, KEK, Tsukuba, Japan

There is a meeting toward a J-PARC proposal on high-energy hadron
physics on March 12 before the main workshop. Wen-Chen Chang,
Jen-Chieh Peng, Shin'ya Sawada, and other people have been
studying on a possible proposal. We discus topics on high-energy
hadron physics, especially on exclusive (and inclusive) Drell-Yan,
... and related topics at this meeting. You may also join this meeting
if you are interested in the topic.
* We expect to have this meeting at 13:00-17:00 on March 12.


The workshop on hadron physics with high-momentum hadron beams at J-PARC
in 2015 will be held from March 13 to March 16, 2015 at KEK, Tsukuba,
Japan. This workshop is intended to discuss possible hadron-physics
projects by using the high-momentum beamline at J-PARC. The high-momentum
hadron beam was financially approved by the Japanese government in 2013,
and it is expected to be ready in 2016.

We list some physics topics in the following "Possible hadron-physics
topics"; however, any interesting new ideas are welcome from both
theorists and experimentalists.

If you are interested in participating in the workshop,
***** please register by February 6, 2015 *****
especially because the KEK dormitory will be crowded
in the middle of March, 2015.

We are looking forward to seeing you at the workshop.

Sincerely, Shunzo Kumano, Osamu Morimatsu, Kyoichiro Ozawa, Shin'ya Sawada (KEK)


High-momentum beamline
The high-momentum beamline can transport the primary proton beam (30 GeV)
with the intensity of 10^10 - 10^12/sec to the Hadron Hall, and it is
a branch from the main proton beam of 10^13 or 10^14/sec. In addition,
by installing a thin production target into the main proton beam
at the branching point, one can obtain unseparated secondary beams
such as pions etc. The beam intensity of these secondaries depends
on its species and momentum. A typical intensity for 10 GeV/c (15 GeV/c)
pions would be in the order of 10^7/sec (10^6/sec) or so. The intensity
for higher momentum beams would be less. The construction of
the beamline has been started.

Possible hadron-physics topics
The following list is just an example of possible projects.
We welcome new ideas on the projects.
* high-energy exclusive processes (GPD, quark counting, ...)
* pQCD, partonic structure of nucleon and nuclei, spin physics
* charmed-hadron physics, intrinsic charm and strange
* hadron properties in nuclear medium
* quark/hadron interactions in nuclear medium
* related theoretical developments
* other ideas on possible projects

For getting a rough idea of discussion topics, you may look at
the previous workshop
In the workshop of 2015, we expect to focus more on each topic toward
new proposals or updates of proposals, especially on
(1) high-energy hadron physics (exclusive reactions, nucleon structure)
(2) charm-production cross sections and spectroscopy
(3) mass modifications and possible relation to chiral symmetry restoration.

have own fund. If you have your own financial source, we hope that
you use it if possible.

Registration fee
The registration fee is 4500-yen (2500-yen for graduate students
and postdocs), including the fee for a get-together party and coffee.
The payment should be done at the registration desk at the workshop
site with CASH (Japanese Yen) only.
Please note that the registration fee cannot be supported for
all the participants due to a KEK regulation because it is
for the banquet, coffee, and snacks.

(How to reach KEK)
    http://www.kek.jp/ja/Access/ (Japanese)

Please read the access information from the Narita/Haneda airports at

If you arrive at the Narita/Haneda international airport,
you need to take a bus (or train) from the airport to the Tsukuba center
Then, you may take a bus
or you may take a taxi to the hotel or KEK.
The taxi cost is about 3500 yen. It would be a good idea to show
the map of the hotel or KEK to the taxi driver by printing out
the access information page of the hotel web or KEK.
If you stay at the Urban hotel, there is a hotel limo to take
you from the Tsukuba center to the hotel. Please call the hotel
to inform your schedule after you arrive in Japan.

Registration for wireless LAN
You need to register the MAC address of your notebook computer
for using LAN at KEK in advance from the following web site:
    https://krs.kek.jp/uskek/ui/ (Japanese).
