1. HP-SEE DISSEMINATION & TRAINING Tirana, 27 March 2012
HMLQCD Hadron Masses from Lattice QCD University of Tirana A.Borici , D.Xhako, R.Zeqirllari EC FP7 Project HP-SEE

2. Introduction Strong interaction
one of the fundamental forces in Nature
(gravity, electromagnetic, strong, weak)
dynamics between quarks and gluons
quark proton neutron nucleon

3. Quarks Elementary particle and a fundamental constituent of matter.
Combine to form composite particles called hadrons
Color confinement 
Asymptotic freedom
How quarks and antiquarks interact?

4. Quark – Antiquark potencial
V(r) = kq/r (electro-magnetic interaction)
V(r) = V0 + Kr + /r
Define V0, K,  and model the quark antiquark potencial

5. Calculations and results
Lattice volume 84
 = 5.7
N = 100
Calculation of Wilson’s loops
Calculation of potencial’s values
Best fit of the datas

6. Results: Quark – Antiquark potencial, =5.7

7. Results and conclusions
Execution time t=5h:40 min
The program scales up to 4 processors
Need for further optimization of the code
