Abstract: Many BSM models predict new
long-lived particles that could be produced at the LHC and travel
measurable distances before decaying. This talk will focus on a set
of low-background searches for long-lived particles using the LHC
Run 2...
Abstract: Meromorphic amplitudes are the
simplest non-trivial scattering amplitudes. They describe the
exchange of infinitely many higher spin resonances in theories like
string theory and large N gauge theories. Yet, despite being very
simple...
Abstract: I will describe constructions of
lattice field theories that assign a single bosonic variable to
each site, rather a conjugate pair x,p. The information to realize
a non-trivial dynamics is realized by non-trivial Poisson brackets
between...
Abstract: I will discuss work in progress with
M. Disconzi on spherically symmetric solutions to the Einstein–
Euler equations. The main result is local well-posedness for a
class of initial data satisfying the physical vacuum condition.
This is the...
Abstract: I will summarize recent results on
the large N limit of path integrals of 3d SCFTs arising on the
worldvolume of N M2-branes placed on compact Euclidean manifolds.
The leading N^3/2 term in the large N expansion of these "free
energies"...
Abstract: The Miura transformation is a
powerful formalism to construct generators of vertex operator
algebras in free field representation. In this talk, I will explain
that Miura operators are R-matrices of a certain quantum algebra,
and comment...
Abstract: I will introduce two new
families of critical string theories in two dimensions and explain
that, when viewed as two-dimensional quantum gravity on the
worldsheet, each is equivalent to a matrix model. The first
worldsheet string theory...
Abstract: In 2022, the Event Horizon Telescope
collaboration revealed the first images of the shadow of our Milky
Way supermassive black hole, Sagittarius A* (Sgr A*). Since its
detection in the mid-70s, this bright radio source in the
Galactic...
