Dear participants,
<div class=""><br class="">
</div>
<div class="">The derivation of the cross section in classical physical has been inspired by: </div>
<div class=""><a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__web.physics.ucsb.edu_-7Efratus_phys103_LN_Scattering.pdf&d=DwMGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=YnbWT6eYw3Qao8Pp1mGxH1qMgf2ysgTRlvO73ShFdVI&m=Twk3rjO8K6w_olyoeFx5dtavQGRtKRJpzGE3ENGKHjjuR3GofSigmqtX68YlQi-3&s=K3mwp0-LpMiCsEykvqB6n-jAYcd58YJM_jpr-QkD7Jc&e=" class="">http://web.physics.ucsb.edu/~fratus/phys103/LN/Scattering.pdf</a></div>
<div class=""><br class="">

<div class="">The derivation of the cross section in relativistic theory is presented in various books:</div>
<div class="">The one by <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__books.google.es_books-3Fid-3DGRd5AAAAIAAJ-26q-3Dmartin-2Band-2Bspearman-26dq-3Dmartin-2Band-2Bspearman-26hl-3Den-26sa-3DX-26redir-5Fesc-3Dy&d=DwMGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=YnbWT6eYw3Qao8Pp1mGxH1qMgf2ysgTRlvO73ShFdVI&m=Twk3rjO8K6w_olyoeFx5dtavQGRtKRJpzGE3ENGKHjjuR3GofSigmqtX68YlQi-3&s=rwuusN2hv8iLw7k0qq2egpySS8CWZVu0RvqVsiCJrq4&e=" class="">Martin and Spearman</a> in Chapter 4.2</div>

<div class="">A more rigorous treatment (as well as the derivation of the Dalitz plot) is given in <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__books.google.es_books-3Fid-3DMSdywQEACAAJ-26dq-3DWeinberg-2Bquantum-2Bfield-2Btheory-26hl-3Den-26sa-3DX-26redir-5Fesc-3Dy&d=DwMGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=YnbWT6eYw3Qao8Pp1mGxH1qMgf2ysgTRlvO73ShFdVI&m=Twk3rjO8K6w_olyoeFx5dtavQGRtKRJpzGE3ENGKHjjuR3GofSigmqtX68YlQi-3&s=n8dBhRAAJ9O5uclKCy_qib0BPslM4GqG9KBFRUqDC08&e=" class="">Weinberg’s book</a> chapter 3.4 </div>
