Thank you very much for your participation and contributions to the workshop. We would like to ask your cooperation on "Acknowledgements" in your papers and your work motivated by the YITP/YIPQS workshop. Workshop participants are also encouraged to add Yukawa Institute as your affiliation in the paper motivated by the workshop.

Examples:

• The authors thank the Yukawa Institute for Theoretical Physics, Kyoto University, where this work was initiated [or completed] during the YITP-T-14-03 on “Hadrons and Hadron Interactions in QCD"
• The authors thank the Yukawa Institute for Theoretical Physics, Kyoto University. Discussions during the YITP workshop YITP-T-14-03 on “Hadrons and Hadron Interactions in QCD" were useful to complete this work.

We are going to organize a long-term workshop entitled "Hadrons and Hadron Interactions in QCD -- Effective theories and Lattice -- (HHIQCD2015)" at Yukawa Institute for Theoretical Physics (YITP), Kyoto University, for five weeks, from Feb.15 (Sun) to Mar.21(Sat), 2015.

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.

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.

A 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
