Abstract: In this talk, I will review a recent
progress on the use of the Amplituhedron construction to calculate
four-point scattering amplitudes in the planar N=4 SYM theory. This
uses a novel expansion of the loop integrand using negative...
Abstract: Powerful techniques have been
developed in quantum field theory that employ algebras of local
operators, yet local operators cannot create physical charged
states in gauge theory or physical nonzero-energy states in
perturbative quantum...
Abstract: The 1+1-dimensional adjoint QCD
theory (namely SU(N) gauge theory coupled to a Majorana fermion in
the adjoint representation of the gauge group) has two curious
properties. When the fermion is massless, the theory exhibits
screening of...
Abstract: What is the mathematical question
about the S-matrix to which string amplitudes are the answer?
In this talk, I will show that both the four-point Veneziano and
Virasoro-Shaprio amplitudes, along with the string spectrum itself,
are the...
Abstract: AI progress is accelerating, and now
the leaders expect “artificial general intelligence” (AGI) in 2 to
3 years. While difficult to believe, we must prepare for the
possibility. We can take some lessons from previous episodes in
which...
Abstract: Despite the undeniable success of the
Large Hadron Collider (LHC), Beyond the Standard Model (BSM)
physics remains elusive. In this talk, I will outline a
multifaceted strategy to maximize discovery potential at current
and future high...
Abstract: I will start with a broad overview of
the theory of initial conditions of the universe, what we know and
what we hope to know in the near future.
Then I will describe some recent work. Motivated by precision
calculations in primordial...
