lately higgs is found
than how about string theory
example string's position
strings will destroy??

Is this a haiku?? :smile:

String theory, if it has any value, deals only with physics at extremely high energy, near the Planck scale. It doesn't tell us anything about what to expect from LHC results, and the LHC does not help us understand string theory.
 
i need more ..

You need more WHAT ?

Your question doesn't make any sense, so it is difficult to know what it is you intend to ask.
 
specific i want to know is
higgs give mass to particle but
string also say it can choose
mass by vibration
and somebody say string theory
made assume standars is wrong
i am curious about these two
 
Higgs mechanism is an interaction which gives mass to some massless particles. This can be achieved in string theory: some string states are massless, but then acquire mass through Higgs mechanism. String states which are intrinsically massive are mostly multiples of the Planck mass so they are short-lived and far beyond detection.
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
