Theory Advances in BSM Physics / McCullough, Matthew (CERN)
Rather than attempting to summarise the full spectrum of recent advances in Beyond the Standard Model (BSM) theory, which are many, in this talk I will instead take the opportunity to focus on two frameworks related to the hierarchy problem currently receiving significant attention. [...]

Charm in Deep-Inelastic Scattering / Ball, Richard D (U. Edinburgh, Higgs Ctr. Theor. Phys. ; CERN) ; Bonvini, Marco (Oxford U., Theor. Phys.) ; Rottoli, Luca (Oxford U., Theor. Phys.)
We show how to extend systematically the FONLL scheme for inclusion of heavy quark mass effects in DIS to account for the possible effects of an intrinsic charm component in the nucleon. We show that when there is no intrinsic charm, FONLL is equivalent to S-ACOT to any order in perturbation theory, while when an intrinsic charm component is included FONLL is identical to ACOT, again to all orders in perturbation theory. [...]

The Standard Model Higgs as the origin of the hot Big Bang / Figueroa, Daniel G (CERN) ; Byrnes, Christian T (Sussex U., Astron. Ctr.)
If the Standard Model (SM) Higgs is weakly coupled to the inflationary sector, the Higgs is expected to be universally in the form of a condensate towards the end of inflation [...]

Large $N$ topologically twisted index: necklace quivers, dualities, and Sasaki-Einstein spaces / Hosseini, Seyed Morteza (Milan Bicocca U. ; INFN, Milan Bicocca) ; Mekareeya, Noppadol (CERN)
In this paper, we calculate the topological free energy for a number of ${\mathcal N} \geq 2$ Yang-Mills-Chern-Simons-matter theories at large $N$ and fixed Chern-Simons levels. [...]

Three-Index Symmetric Matter Representations of SU(2) in F-Theory from Non-Tate Form Weierstrass Models / Klevers, Denis (CERN) ; Taylor, Washington (MIT, Cambridge, CTP)
We give an explicit construction of a class of F-theory models with matter in the three-index symmetric (4) representation of SU(2). [...]

Single and double inclusive forward jet production at the LHC at $\sqrt{s}$ = 7 and 13 TeV / Bury, Marcin (Cracow, INP) ; Deak, Michal (Cracow, INP) ; Kutak, Krzysztof (Cracow, INP) ; Sapeta, Sebastian (Cracow, INP ; CERN)
We provide a description of the transverse momentum spectrum of single inclusive forward jets produced at the LHC, at the center-of-mass energies of 7 and 13 TeV, using the high energy factorization (HEF) framework. [...]

Stop searches in flavourful supersymmetry / Crivellin, Andreas (PSI, Villigen ; CERN) ; Haisch, Ulrich (Oxford U., Theor. Phys. ; CERN) ; Tunstall, Lewis C (CERN)
Natural realisations of supersymmetry require light stops ${\tilde t}_1$, making them a prime target of LHC searches for physics beyond the Standard Model. [...]

Several searches have found evidence of $^{60}$Fe deposition, presumably from a near-Earth supernova (SN), with concentrations that vary in different locations on Earth. [...]
