(a) E_cm = [ (E_1+E_2)^2 - ( p_1_vector + p_2_vector)^2]; I think yes. E_2 is just rest mass energy of proton. (b) E_cm = [ E_1^2 + 2*E_1*E_2 + E_2^2 - p_1^2 - p_2^2 -2*p_1*p_2* cos (90 degree) ]^(1/2) = [ ( E_1^2 - p_1^2) + ( E_2^2 - p_2^2) + 2* E_1 * E_2 ]^(1/2)...

Suppose a single hydrogen atom is in mixed state. Ψ=(1/√2) Ψ_100+(1/√2) Ψ_200 Then energy will be E=(1/2)*13.6+(1/2)*(3.4)=8.5 eV. But there is no spectral line at 8.5 eV.

Hi I am a physics graduate student. Recently I am learning representation theory of groups. I understand the basic concepts. But I need a good book with lots of examples in it and also exercise problems on representation theory so that I can brush up my knowledge.The text we follow is "Lie...

No I want full resolution.Because for 500*500 case boundaries in image is not sharp enough for experimental purpose.

I am creating a gray-scale image of a 2000*2000 matrix using mat2gray and imshow command.But highest number of matrix entries that imshow can implement is 500*500 approximately.After that it shows------ "Warning: Image is too big to fit on screen; displaying at 8% > In...

I am physics student.I know basic definition of topological space.I want a book(or may be any web note or video lecture) where topology spaces of various groups are rigorously discussed.

"Volume of a primitive cell is independent of the choice of the cell." Why?

I am thinking to do a project on theoretical study of Neutron Scattering.But I cannot decide a particular topic. Please refer me with some topic names.

I am a graduate student and I am thinking of doing a project on "Inelastic neutron scattering and density functional theory". Can you please inform me what are the exact background knowledge(courses) I should have to.

I want a book on particle physics which contains lots of theoretical calculations.All books recommended in my class contain lots of experimental techniques and very little about theory.I like "Introduction to Elementary Particles" by D Griffiths.Is there any book like Griffiths?

I completed the book 'Nonlinear Dynamics and Chaos' by Strogatz. What will be next good book to learn about nonlinear dynamics?

In multivariate probability distribution the first two cumulants are the means and covariances.Higher-order cumulants contain information of decreasing significance, unlike higher-order moments.We cannot set all moments higher than a certain order equal to zero since E(X^2n)>=E(X^n)^2 and...
