From strings in 6d to strings in 5d
We show how recent progress in computing elliptic genera of strings in six
dimensions can be used to obtain expressions for elliptic genera of strings in
five-dimensional field theories which have a six-dimensional parent. We further
connect our results to recent mathematical results about sheaf counting on
ruled surfaces.Comment: 17 pages, 4 figures. v3: Definitions clarified, Section "Concluding

Search for heavy neutral CP-even Higgs within Type-IV 2HDM at a future linear collider
In this paper, the production process is analyzed
in the context of the type IV 2HDM and the question of observability of a
neutral CP-even Higgs boson at a linear collider operating at
TeV is addressed. The CP-odd Higgs is assumed to experience a gauge-Higgs decay
as with hadronic decay of boson as the signature of
signal events. The production chain is thus where is a or . Four
benchmark points with different mass hypotheses are assumed for the analysis.
The Higgs mass is assumed to vary within the range 150-300 GeV in
increments of 50 GeV. The anti- algorithm is used to perform the jet
reconstruction. Results indicate that the neutral CP-even Higgs is
observable through this production mechanism using the di-muon invariant mass
distribution with possibility of mass measurement. The corresponding signal
significances exceed at integrated luminosity of 3000 .Comment: 23 pages, 18 figures, 10 table
M5 branes and Theta Functions
We propose quantum states for Little String Theories (LSTs) arising from M5
branes probing A- and D-type singularities. This extends Witten's picture of M5
brane partition functions as theta functions to this more general setup.
Compactifying the world-volume of the five-branes on a two-torus, we find that
the corresponding theta functions are sections of line bundles over complex
4-tori. This formalism allows us to derive Seiberg-Witten curves for the
resulting four-dimensional theories. Along the way, we prove a duality for LSTs
observed by Iqbal, Hohenegger and Rey.Comment: 27 pages, 1 Figure. v3: included further explanations and corrected
