In the context of massive quantum field theories\, I will derive high energy bounds on relative entropy as well as study the Re gge behavior. Then I will turn to the S-matrix bootstrap. I will give a br oad overview of what this program is about and how to constrain pion scatt ering with it. Here\, some insight from relative entropy will prove to be handy to constrain the space of S-matrices. I will discuss some ideas base d on minimization of total scattering cross-section to constrain pion S-ma trices further\; curious coincidences such as boundary of allowed S-matric es being close to the Lovelace-Shapiro model of early string theory\, emer ging linear Regge trajectories\, as well as reduction in Entanglement powe r near the standard model point will be discussed.\n LOCATION:https://researchseminars.org/talk/HET/6/ END:VEVENT END:VCALENDAR
