The Bootstrap Siege of M-theory

Andrea Guerrieri
(City University )
Abstract
In recent years, analytic and numerical Bootstrap methods have emerged as powerful tools to probe non-perturbative aspects of quantum field theory and quantum gravity. In this talk I will discuss the nonperturbative S-matrix Bootstrap approach to scattering amplitudes in maximal supergravity. After a brief overview of the method, I will review earlier results obtained in this framework, including bounds on the Wilson coefficient of the R^4 operator in D=9,10,11, and the observation that string and M-theory amplitudes appear to lie on the boundary of the allowed bootstrap region. I will then present preliminary results for the higher dimensional corrections like the D^4 R^4 interaction in eleven dimensions and show how the resulting constraints on the non-perturbative M-theory scattering amplitude match expectations from string/M-theory.


 

Research survey - teaching practices, student motivation and personality traits in undergraduate STEM

Participants are needed for an MSc in Education dissertation project that explores the relationships between teaching practices, student motivation and student personality traits in undergraduate STEM courses. 

Participation in this study includes the completion of a questionnaire, which will ask you questions about your beliefs and attitudes in relation to the above-mentioned topics. Please think carefully about each item and answer as truthfully as possible based on your current feelings.

Oxford Science Innovation Summit 2026

The Oxford Physics Society is hosting an ‘Oxford Science Innovation Summit’ at midday on Sunday 8th March 2026 in the L1 in the Mathematical Institute.

Exam Orientation sessions

St Luke's ChapelFor any students due to sit their exams in Weeks 4-9 of Trinity term in a 'small room' venue, this venue will be St Luke's Chapel, just outside the Mathematical Institute. 

End of term feedback questionnaire

As the end of term approaches, we would like to request your feedback on the lectures and classes you have attended this term. This is a chance to give us detailed feedback on what has worked well, what could be improved, and what your experience has been like.

OxWIM Day

The third annual Oxford Women and Non-Binary People in Mathematics Day (OxWIM Day) ran very successfully on the 28th of February in the Andrew Wiles Building. This year’s theme was ‘Shaping Success’ and explored the many ways underrepresented genders can define their own success within a mathematical career.
