A new application of the Thomas–Fermi (TF) statistical quark model is described, similar to a previous application to baryons. The main usefulness of this model will be to detect systematic energy trends in the composition of the various particles. It could be a key to identifying families ...
Baryons are characterized by abaryon number,B,of 1. Their antiparticles, calledantibaryons, have a baryon number of −1. Anatomcontaining, for example, oneprotonand oneneutron(each with a baryon number of 1) has a baryon number of 2. In addition to their differences incomposition, baryon...
At freezeout, the system has become so dilute that the mean-free path, λ, is larger than L, the system size, and the application of hydrodynamics to the system is no longer valid. The particles no longer interact but simply move away from each other on linear trajectories. This is the...
The unmatter does exists, for example some messons and antimessons, through for a trifling of a second lifetime, so the pions are unmatter (which have the composition u^d and ud^, where by u^ we mean anti-up quark, d = down quark, and analogously u = up quark and d^ = anti...
The structure and basic properties of dense nuclear matter still remain one of the open problems of Physics. In particular, the composition of the matter that composes neutron stars is under theoretical and experimental investigation. Among the theories that have been proposed, apart from the classi...
Nowadays, it has become a common phenomenon to explore the inner core of NSs assuming that it is composed of deconfined quark matter taking into account the clear mass-radius window imposed by the data from the Neutron Star Interior Composition Explorer (NICER) [4,5,6] and the gravitational...
Due to the air composition and main components of the UHECR the passage of UHECR particles through atmosphere can be considered as collision mostly small systems. It should be emphasized collisions at ultra-high en- ergies can lead to creation of QGP even in light nuclear interactions [1]. ...
of rock ups and downs, the last play, is a deep woody composition, cedar wood, amber and vanilla, let it rock melody distributed energy, and the most warm smell of ending, let the fragrance spectrum out of a rock, let the listener with the music rhythm, feeling of ANNA SUI rock ...
In the Standard Model of particle physics, the strength of the couplings of the b quark to the u and c quarks, |Vub| and |Vcb|, are governed by the coupling of the quarks to the Higgs boson. Using data from the LHCb experiment at the Large Hadron Collide
