THEORETICAL considerations suggest that the square root of mass may be more interesting and important than mass itself in the case of the ultimate particles of matter. For in the modern theory of matter, electric charge is more fundamental than mass, and the dimensional formula for electric ...
Relative Momentum of Quarks in Mesons at Center of Mass Frame When we study the bound state of quarks, i.e. mesons, the relative momentum is given as; q=1/2(p1-p2). Where p1 and 2, are momentum of quark and anti-quark, respectively.My question is, what is the value of q at ce...
The decay rates for $B^0 \\to K^+ \\pi^-$, $B^+ \\to K^0 \\pi^+$, and the charge-conjugate processes were found to provide information on the weak phase $\... M Gronau,JL Rosner - 《Phys.lett.b》 被引量: 46发表: 2000年 The X(2175) as a resonant state of the $\...
Hi guys, I consider the qm-derivation of the electronic states of hydrogen. There are two different derivations (I consider only the coulomb-force): 1) the proton is very heavy, so one can neglect the movement 2) the proton moves a little bit, so one uses the relative mass ##\mu##...
In a soil–water mixture, a water molecule has the ability to either store energy (i.e., charge storage capacity) or release heat as a loss of energy when exposed to an EM field, which influences the EM wave and helps in measurement of εr. The εr is a dimensionless number that ...
The higher the mass of the particle, the narrower the dose-weighted lineal energy spectra and the larger the shift to high lineal energy values. A shift of the spectra in high y values would represent an increase in the aggressiveness of the event, i.e. inducing more frequently lethal ...
VOCs were measured using an Ionicon proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS), a new system that allows for VOC measurements at high time (<1 s) and mass (>5000 d/dm) resolution, high sensitivity and an ultra-low detection limit [46]. The PTR-TOF-MS (PT...
So that the results described in this section can be reconstructed at pH = 7, the standard molal Gibbs energies () and net charges of ionized proteins at this pH are listed in Table 1. In Figs. 1a and 1b the metastable equilibrium predominance limits of ionized proteins in the ...
