There are two problems in this set. The first problem is fully solved with nothing left to imagination.It also demonstrates how solution to this class of problems should be presented.
A soft copy was mailed to the students. They are expected to go through and understand the solution to the first problem in advance. The students were required to print out the second problem and come to the class with a print out.Alternatively a print copy of problem #2 can be provided. In the class the first one they could read from PDF files on their mobiles.
They are required to complete the details of the second problem during the class by filling the gaps as indicated by ??? marks in red.
This format of tutorial was tested in the way descried above for a summer course in 2018 at Univeristy of Hyderabad. Most of the students could complete in one hour and found this format very helpful.

There are several important, useful , interesting and lesser known facts that are scattered over text books and jorunals devoted to teaching and learning. These facts are closely connected to topics covered by most text books and to topics that are covered in every standard course.
This series of short BLOGS "Did You Know That .." draws attention to important and interesting facts related to text book topics. These are taken mostly from Journnals and text books. References are provided
QuestionConsider a system of two real scalar fields \(\phi_1, \phi_2\) described by the Lagrangian density\begin{equation} \Lsc = \frac{1}{2} \partial_\mu \phi_i \partial^\mu \phi_i - \frac{1}{2} m^2 \phi_i\phi_i -\frac{1}{4} \lambda (\phi_i\phi_i)^2.\end{equation}Compute the scattering cross section to the lowest order in \(\lambda\). Find the cross sections for the three processes
Write your answers as a constant times \(\sigma_0\equiv \frac{\lambda^2}{64\pi s}\) where \(s\) is the total energy in the center of mass frame.
Answer : a. \(4\sigma_0\) b. \(36 \sigma_0\) c. \(4 \sigma_0\)
Hint : Find symmetry appropriate factor.Remark : Good question
