Hello! Does anyone know whether in the current phase of String Theory, there are any equations that would enable us to calculate half-lives of a given a particle or isotope?

Hello! I have just been wondering if each of the isotopes of an atom is determined by its proton (Z) and neutron number (N), then wouldn't these two numbers be enough to calculate the half-lives of them (given of course the masses of the proton and neutron also)? So, how does current...

thanks for all your answers, quantum mechanics and high energy physics is indeed really interesting! i've just found another article, which reports the initial findings of a nucleus of A=292 and atomic number Z=~122, whose half-life is: t1/2 >= 10^8 y (just to get an idea what orders of...

alright then, but what chance do you give the newly starting Large Hadron Collider in Geneva, that it will discover super-heavy baryons that will be much more stable than expected?

if neither of your (even the very technical) textbooks mention scc, ssc, btt or bbt then wouldn't it be unexplored or perhaps somewhat ignored territory? why would it be important? wouldn't a 2nd and/or 3rd generational equivalent of the periodic table be interesting? couldn't some new...

i wasn't talking about hyperons (any baryon containing a strange quark, but no charm quarks or bottom quarks!) but such discoveries (that contradict accepted dogmas) could open a very narrow but extremely important window into yet unexplored territory (eg.: the strange & charming and the top &...

here is the technical article: http://arxiv.org/abs/hep-ex/0406045

look, I've just read a very interesting article about a new particle (composed of a charming and a strange quark), and surprisingly, they found that it lived much longer than what theory had previously suggested... (a heavier and more stable particle than in theory!)...

so are you suggesting then, that theoretically they might be possible... but these hadrons may not exist on our time scale... (what about the time scale of string theory?) how long would the "hadronization process" have to take? thanx, and you have any more books on hadrons, you'd recommend?

So, why can't top quarks be bound in a hadron?? (the strong interaction keeps the quarks in the proton and neutron also...)

I understand that is the most likely thing that can happen, but then there is the so-called "Island of Stability" at the far end of the periodic table, which implies that even very high energy elements could be yet stable...

Hello! I have a very interesting question, whose answer I have not yet been able to find out. Now, according to The Standard Model there are three generations of matter, therefore three generations of quarks also. Generations of Quarks: 1st: up (u) & down (d) 2nd: charming (c) &...
