1. Symmetries of celestial amplitudes / Stieberger, Stephan ; Taylor, Tomasz R.
Celestial amplitudes provide holographic imprints of four-dimensional scattering processes in terms of conformal correlation functions on a two-dimensional sphere describing Minkowski space at null infinity. [...]

2. Strings on celestial sphere / Stieberger, Stephan ; Taylor, Tomasz R.
We transform superstring scattering amplitudes into the correlation functions of primary conformal fields on two-dimensional celestial sphere. [...]

3. New relations for Einstein–Yang–Mills amplitudes / Stieberger, Stephan ; Taylor, Tomasz R.
We obtain new relations between Einstein–Yang–Mills (EYM) amplitudes involving N gauge bosons plus a single graviton and pure Yang–Mills amplitudes involving N gauge bosons plus one additional vector boson inserted in a way typical for a gauge boson of a “spectator” group commuting with the group associated to original N gauge bosons. [...]

4. Update on 750 GeV diphotons from closed string states / Anchordoqui, Luis A. ; Antoniadis, Ignatios ; Goldberg, Haim ; Huang, Xing ; et al
Motivated by the recent update on LHC searches for narrow and broad resonances decaying into diphotons we reconsider the possibility that the observed peak in the invariant mass spectrum at Mγγ=750 GeV originates from a closed string (possibly axionic) excitation φ (associated with low mass scale string theory) that has a coupling with gauge kinetic terms. [...]

5. 750 GeV diphotons from closed string states / Anchordoqui, Luis A. ; Antoniadis, Ignatios ; Goldberg, Haim ; Huang, Xing ; et al
We show that low-mass-scale string compactifications, with a generic D-brane configuration that realizes the standard model by open strings, can explain the relatively broad peak in the diphoton invariant mass spectrum at 750 GeV recently reported by the ATLAS and CMS Collaborations. [...]

6. Disk scattering of open and closed strings (I) / Stieberger, Stephan ; Taylor, Tomasz R.
At the tree level, the scattering processes involving open and closed strings are described by a disk world-sheet with vertex operator insertions at the boundary and in the bulk. [...]

7. Subleading terms in the collinear limit of Yang–Mills amplitudes / Stieberger, Stephan ; Taylor, Tomasz R.
For two massless particles i and j , the collinear limit is a special kinematic configuration in which the particles propagate with parallel four-momentum vectors, with the total momentum P distributed as pi=xP and pj=(1−x)P , so that sij≡(pi+pj)2=P2=0 . [...]

8. Stringy origin of diboson and dijet excesses at the LHC / Anchordoqui, Luis A. ; Antoniadis, Ignatios ; Goldberg, Haim ; Huang, Xing ; et al
Very recently, the ATLAS and CMS Collaborations reported diboson and dijet excesses above standard model expectations in the invariant mass region of 1.8–2.0 TeV. [...]

9. Graviton amplitudes from collinear limits of gauge amplitudes / Stieberger, Stephan ; Taylor, Tomasz R.
We express all tree-level graviton amplitudes in Einstein's gravity as the collinear limits of a linear combination of pure Yang–Mills amplitudes in which each graviton is represented by two gauge bosons, each of them carrying exactly one half of graviton's momentum and helicity..

10. Graviton as a pair of collinear gauge bosons / Stieberger, Stephan ; Taylor, Tomasz R.
We show that the mixed gravitational/gauge superstring amplitudes describing decays of massless closed strings – gravitons or dilatons – into a number of gauge bosons, can be written at the tree (disk) level as linear combinations of pure open string amplitudes in which the graviton (or dilaton) is replaced by a pair of collinear gauge bosons.
