Investigation and analysis of lambda proton binding energy Mohadeseh Sadat Navabi m30navabi@gmail com Date of Submission July 1 2019 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr M Hassanvand Email Hassanvand@cc iut ac irAbstractSo far many researchers have studied the bound three and four nucleon systems and using two and three nucleonforces they have applied the different methods to calculate the binding energy of such systems Determining thestability or in fact the binding energy of single lambda proton hyperon p is the main goal of the currentresearch Most of the Hyperon Nucleon interactions Y N are the One Boson Exchange interaction OBE which is obtained using the YN and NN data in the same direction In this project the potential of and protonis very important and for this two body system we applied the expansion of Gaussian basis First we consideredthe Gaussian potential domains as our initial computing data and because the potentials are complex they areassumed to have real and imaginary parts Then using Schr dinger equation and performing the correspondingcalculations we obtained the binding energy of the particles And at the end of the calculations the real part ofthe energy is the main answer and the imaginary part is the width Also by repeating the calculations we canchange the number of Gaussian basis to achieve the optimal answer Here the number of Gaussian basis N 30is the optimal answer for the correct binding energy correspond to the binding energy of other researches Finally using these methods and comparing the results of the efforts made in this field we evaluated the values obtainedfor the binding energy of and p For example for the potential amplitude 01 3770MeV with a Range 0 3fm the binding energy obtained 1 59 165MeV and for 02 1160MeV with a Range 0 2 fm thebinding energy is equal to 2 50 39MeV which corresponds to the values reported in previous works 51 Keywords Multi nucleon systems Potential of particles the expansion of Gaussian basis Binding Energy of
