BackgroundWorkshop "Progress in computational physics---Bridge between MACRO and MICRO
3rd - 5th, Dec, 2011 Ise, Shima, JAPAN

There are lots of works on nuclear EOS.
You can find about 300 papers tiled “EOS” in arXiv in thisdecade, while we have 15 EOS tables.
Lattimer-Swesty EOS, Shen EOS and their friends arestill mainly used in astrophysical studies, neverthelessfine EOSs are NOT always tabulated.
What causes this situation?
The answer is the cost of tabulating EOS for large grids.
We should be free from EOS tables...

Worth constructing EOS DB!?
In addition to the above, exp. data and obs. data related toEOS are now increasing as shown in next slides.

EOS Problem from NS Obs.
Recent problems of nuclear EOSs for compact objects”The most of nuclear EOS proposed can not support 2Msum NSwith strangess or quarks”“MR relation derived from NS obs permit only LS EOS”
- Is that true? Why not?
Obs. difficulty to decide R-model dependent
Inconsistency with HIC exp.
- gamma 0.26 from NS Obs

Workshop "Progress in computational physics---Bridge between MACRO and MICRO
3rd - 5th, Dec, 2011 Ise, Shima, JAPANThe point is...
How do we share these information on EOS,
NS obs. data and HIC exp. data?
What do we care about when we see these data?
e.g.)assumptions, physical conditions, calc.
In EOS DB, we categorize each EOS according to-their theo. background such as framework
for “high/medium/low” densities and/or temperatures...(1),-“rel./non-rel.”...(2),-off course their framework such as LDM, HF, RHF etc...(3)What Database can do is ....

Expected EOS discussion with EOS DB
Using our classifications,
we may find unknown aspects of EOS models
on the web as shown in the previous slide,besides we can customize EOS for compact objects
within exp./obs. constraints by using EOS DB.
as a tool(Lattice QCD, HIC exp. and NS Obs.)+(Bayesian Analysis) = the most probable EOS
The EOS will allow us the following discussions;
1. Internal structure of NS from phenomenological
Lagrangian by fitting the above EOS(missing higher order effects or int. strength)
2. NS radius by OV eqn. and observed NS massphysics
