DESCRIPTION:Speakers: Vyacheslav Dokuchaev (Institute for Nuclear Research
  of the Russian Academy of Sciences)\nMatter consists of particles and fie
 lds\, and more consistently only of quantum fields. Particles are the loca
 lized excitations of quantum fields. Sometimes fermions are called ``matte
 r’’ and bosons are called ``fields’’. Definition:  the component o
 f the Universe is called ``dark’’ if it does not emit the light. \n\n{
 \\bf Basic components of observable Universe}: \n\n70\\% is the `dark fiel
 d’ or `Dark Energy’ (DE)\, which is the dominating component of the Un
 iverse in the modern Standard Astrophysical Model (named also the Cosmolog
 y of High Accuracy). Dark Energy is either filling up all Universe with ne
 gative pressure\, p95$\\%) is unknown!\n\nThe incomplete and replenished l
 ist of Dark Energy models:\n\nGeneral Relativity framework:\nquintessence 
 DE\, $k$-essence DE\, Born-Infeld DE\; BKS condensate DE\, ghost- condensa
 te DE\, et al.\n\nGeneral Relativity modifications:\n$f(R)$ gravity DE\, G
 auss-Bonnet DE\, holographic gravity\, super-string gravity\, quantum-enta
 ngled gravity et al.\n\n%The term ``Dark Energy'’ is ungrammatical. Ther
 e must be some carrier for energy. The energy itself can not be ``dark’'
  or ``bright’'. \nIt is more reasonable to say on the ``dark field’' o
 r ``invisible field'’.\nMeanwhile\, the term ``Dark Energy'’ becomes c
 onventional and accepted by scientific community.\n\nInterpretation of the
  experiment is impossible without theoretical models\, ideas and concepts.
  The problem of ``Dark Energy’' is the interrelation between the experim
 ent and the theory!\n\nTheoretical modeling is based on:\n(1) Scientific m
 ethod: experiment as criterion of truthfulness (Francis Bacon and Karl Pop
 per)\; (2) criterion of beauty: the theory must be beautiful (Occam’s ra
 zor)\; (3) Criterion of novelty: the theory must be novel and must provide
 s new effects and phenomena\; (4) criterium of liberty: all is allowed\, i
 f not forbidden.\n\n{\\bf After all\, what is Dark Energy? We don’t know
