The Cosmological Grassmannian

Guilherme Leite Pimentel
(Pisa SNS)
Abstract
I will show how a Grassmannian turns out to be the natural kinematic space for describing correlation functions of massless spinning particles, in four dimensional (Anti)-de Sitter space.
In this kinematic space, tree-level cosmological correlators factorize in a simple way and can be bootstrapped with rather ease, revealing some hidden beauty.

The Interim Head of the Equality and Diversity Unit, Marilyn Verghis, is delighted to invite staff and students to an Equali-tea on Tuesday, 1 July from 10.30-11.30am. The tea will be hosted by the Department of Statistics, 24-29 St Giles.

An online staff briefing on proposals for a temporary congestion charge in Oxford have been arranged with the County Council. This will take place at 11.30am-12.30pm on Monday 30 June. Colleagues interested in the proposals and their potential impact are welcome to join using the Teams links provided.

Following a University-wide communications survey in January 2025, the Internal Communications team is inviting staff to take part in follow-up discussion groups or share their views through a short, anonymous questionnaire during July. The aim is to gather more nuanced feedback that will help shape how the University communicates with staff in the future.

Erica Thompson's recent Oxford Mathematics Public Lecture is now available if you want to drop in.
