Dear Colleagues,

This is the first announcement of a long-term workshop,

Hadrons and Hadron Interactions in QCD 
-- Effective theories and Lattice -- (HHIQCD2015)
February 15 (Sun) to March 21(Sat), 2015
Yukawa Institute for Theoretical Physics (YITP), Kyoto University, Japan.

This is a "stay-and-discuss" style workshop in a relaxed atmosphere, 
where each participant is encouraged to stay long and is assigned 
to a desk in an office at YITP. In each day, we will arrange one or two 
seminar sessions, where participants will present their research activities 
including pre-published results. For remaining times other than these sessions, 
participants are free to work on their own researches, to discuss some problems 
with other participants, and even to start new collaborations during the workshop.

This workshop is held under Yukawa International Program for Quark-hadron Sciences. 
The workshop is also held as the Nishinomiya-Yukawa Memorial International Workshop.

* Aims and Scopes

In this workshop, researchers in both lattice QCD and various effective field theories 
come together and make extensive discussions on pros and cons of each method 
for hadron physics, in view of recent progress in both fields. We hope that this 
workshop will bring a new direction of researches, which complementarily employs 
both methods to investigate various properties of hadrons.

* Subjects to be covered

A tentative list of topics in the workshop is as follows.
(1) Hadron structure
- Ground state properties (spectroscopy, masses, form factors, various flavors)
- Exotic structure (heavy quark physics, molecule/multiquark, diquarks)
- Structure functions (PDF, GPD, fragmentations, transition amplitudes)
(2) Hadron interactions
- Meson-baryon/baryon-baryon interactions (ChPT, HQET, lattice)
- Resonances (approach from lattice, Finite volume, Coupling to continuum)
- Scattering and experiments (Extraction resonance/physical parameters, comparison with data)
(3) Many-body systems and matter under extreme conditions
- Nuclear equation of state
- Hadrons in nuclei (Ch-symmetry restoration, U_A(1))
- Hadronic matter and QCD under extreme conditions (density/temperature, strong EM field)
- Constraints from astrophysics
(4) New approaches 
- Precision methods (Isospin breaking, EM effects, Delta I=1/2 rule, BSM)
- Large N QCD, Holographic methods
- Yang-Mills gradient flow (energy-momentum tensor, etc.)
- Lefschetz thimble, complex Langevin 
- Numerical stochastic perturbation theory

* Schedule

The long-term workshop consists of three parts;

1st week & 2nd week (Feb. 16-20, Feb. 23-27): Workshop and one-day mini-symposium
3rd week (Mar. 2-6): symposium
4th and 5th week (Mar. 9-13, Mar. 16-20): Workshop and one-day mini-symposium

In the workshop weeks, we plan to hold one or two seminars a day,
focusing on each subject 
One-day mini symposium.

In the symposium of the third week (Mar. 2-6),
all the subjects and other related topics will be discussed.

* Venue

All the scientific activity at the workshop will be held at
Yukawa Institute of Theoretical Physics (YITP), Kyoto University.
Desks with internet access will be provided to workshop participants.

* Travel
