Some of the fundamental characteristics of elementary particles can be deduced from astrophysical observational data with much higher accuracy than from laboratory experiments. As examples we can mention the upper bounds on the mass of the photon and of different types of neutrinos, restrictions on the...
The collision energy of particles in the frame of the cen- ter of mass results in the formation of new particles and the energy produced in this process is known as the center of mass energy. The center of mass energy of two colliding particles is infinitely high near the event horizon ...
The atomic mass is roughly equal to the sum of which two subatomic particles in an atom?Question:The atomic mass is roughly equal to the sum of which two subatomic particles in an atom?Atomic Structure:At present, the model that is used to describe an atom is the...

We show that the opacity parameter Omega = 4 pi ka/lambda = 2 kX is a more accurate means of demarcating the two emission regimes. Omega is approximately equal to the particle's mean optical depth, and it can be derived from both scattering theory and geometrical optics....
The purpose of this study was to evaluate the in vitro and in vivo dose delivery characteristics of two large porous particle placebo formulations with different mass median aerodynamic diameters (MMAD approximately equal to 3 and 5 μm). In vitro dose delivery characteristics were measured using ...
The reproducibility of the separation experiment was confirmed by repeating the observation several times in the same conditions (Trail 1 ~ 4 in Fig. 3). The mass-independent property of magnetic translation described in equation (1) is an essential factor for achieving separation; that ...
where\(q=e/m\)is the charge-to-mass ratio, the so-called specific charge of the particle. The constants of motion can be determined using timelike and spacelike Killing vectors, and we have $$\begin{aligned} g_{tt}{\dot{t}}+q A_t=-{{{\mathcal {E}}}, \qquad g_{\phi \phi...
As expected the finite quark mass suppresses the quark number susceptibility. We find that at high temperatures T≥600MeV the quark number susceptibility of light quarks and heavy quarks are almost equal in the bottom-up model. This indicates that the heavy quark like charm contribution to ...
