Code for the ttH reconstruction using chi^2

Description

Code used for the ttH reconstruction using 3 different $chi^2$:

• chi3 is a chi^2 with 3 d.o.f which constrains the W_1 and W_2 masses and requires the equality of t_1 and t_2 masses
• chi4 is a chi^2 with 4 d.o.f which constrains the W_1 and W_2 masses and also t_1 and t_2 masses
• chi5 is a chi^2 with 5 d.o.f which constrains the W_1, W_2, t_1 and t_2 masses an also H mass

To Run:
