New frontiers in PDF determination / Ubiali, Maria (speaker) (University of Cambridge)
Parton Distribution Functions (PDFs) are a crucial input at the LHC, their uncertainty often being the limiting factor in the accuracy of theoretical predictions. At the same time the LHC is delivering a number of precise measurements that have the potential to greatly constrain these functions. [...]

Quest for precision in simulations for the LHC / Krauss, Frank Martin (speaker) (University of Durham (GB))
In this talk, I will discuss recent achievements, current challenges and possible future directions in the quest for precision in simulations for the LHC..

Scattering Amplitudes and Worldsheet Models of QFTs / Monteiro, Ricardo (speaker)
I will describe recent progress on the study of scattering amplitudes via ambitwistor strings and the scattering equations. Ambitwistor strings are worldsheet models of quantum field theories, inspired by string theory. [...]

Recent Progress in 3d Gauge Theories / Tong, David (speaker) (University of Cambridge)
QED in d=2+1 dimensions is one of the simplest gauge theories we can write down. It is also hard to solve. [...]

The revenge of the S-matrix / Paulos, Miguel (speaker) (CERN)
In this talk I will describe recent work aiming to reinvigorate the 50 year old S-matrix program, which aims to constrain scattering of massive particles non-perturbatively. I will begin by considering quantum fields in anti-de Sitter space and show that one can extract information about the S-matrix by considering correlators in conformally invariant theories. [...]

Emergence of Symmetries from Entanglement / Latorre, José Ignacio (speaker)
Maximal Entanglement appears to be a key ingredient for the emergence of symmetries. We first illustrate this phenomenon using two examples: the emergence of conformal symmetry in condensed matter systems and  the relation of tensor networks to holography. [...]

The dawn of gravitational wave astronomy / Sperhake, Ulrich (speaker)
On Sep 14 2015, gravitational waves were for the first time detected directly. This observation by the LIGO interferometric detectors marks the dawn of a new era in our observational study of the cosmos as a qualitatively new window to its exploration has been opened. [...]

Supergravity at one loop, anomalies and applications to string phenomenology / Gaillard, Mary K. (speaker) (Berkeley)
I discuss the role of quantum effects in the phenomenology of effective supergravity theories from compactification of the weakly coupled heterotic string. An accurate incorporation of these effects requires a regularization procedure that respects local supersymmetry and BRST invariance and that retains information associated with the effective cut-offs, which have physical meaning for an effective theory [...]
