Reheating after swampland conjecture by Vahid Kamali

“…In the standard model of inflation or cold inflation firstly universe expands where the inflaton rolls the nearly flat part of the potential and in the second part, the universe reheats where the inflaton oscillates around the minimum of the potential which leads to thermalized radiation dominated universe. String theory as the best model of quantum gravity forbids the oscillation around the minimum of the potential during the thermalized epoch of the reheating. …”

Influence of Lorentz Invariation Violation on Arbitrary Spin Fermion Tunneling Radiation in the Vaidya-Bonner Space-Time by Jie Zhang, Zhie Liu, Bei Sha, Xia Tan, Yuzhen Liu, Shuzheng Yang

“…Considering a light dispersion relationship derived from string theory, quantum gravitational theory, and the Rarita-Schwinger equation in the nonstationary spherical symmetry space-time, we derive an accurately modified dynamic equation for fermions with arbitrary spin. …”

U ( 3 ) C... by Luis Alfredo Anchordoqui

“…After that we direct attention to embedding the gauge theory into the framework of string theory. We consider extensions of the standard model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes. …”

“…Abstract We study correlators of insertions along 1/2 BPS line defects in the holographic dual to type IIB string theory in AdS 3 × S 3 × T 4 with mixed Ramond-Ramond and Neveu Schwarz-Neveu Schwarz three-form flux. …”

Non-Gaussianity from Particle Production during Inflation by Neil Barnaby

“…Such interactions are quite natural in a variety of inflation models from supersymmetry and string theory. Using both lattice field theory and analytical calculations, we study the production of χ particles and their subsequent rescatterings off the condensate ϕ(t), which generates bremsstrahlung radiation of light inflaton fluctuations δϕ. …”

Universal flops of length 1 and 2 from D2-branes at surface singularities by Marina Moleti, Roberto Valandro

“…Abstract We study families of deformed ADE surfaces by probing them with a D2-brane in Type IIA string theory. The geometry of the total space X of such a family can be encoded in a scalar field Φ, which lives in the corresponding ADE algebra and depends on the deformation parameters. …”

Susy breaking soft terms in the supersymmetric Pati-Salam landscape from intersecting D6-branes by Mudassar Sabir, Adeel Mansha, Tianjun Li, Zhi-Wei Wang

“…Abstract We investigate the supersymmetry breaking soft terms for all the viable models in the complete landscape of three-family supersymmetric Pati-Salam models arising from intersecting D6-branes on a 𝕋6 /(ℤ2 × ℤ2) orientifold in type IIA string theory. The calculations are performed in the general scenario of u-moduli dominance with the s-moduli turned on, where the soft terms remain independent of the Yukawa couplings and the Wilson lines. …”

Susy at the FPF by Luis A. Anchordoqui, Ignatios Antoniadis, Karim Benakli, Jules Cunat, Dieter Lüst

“…The failure to observe signals of sparticle production at the large hadron collider (LHC) has eroded the central motivation for SUSY breaking at the weak scale. However, String Theory requires SUSY at the fundamental scale $$M_s$$ M s and hence SUSY could be broken at some high scale below $$M_s$$ M s . …”

New approach to strongly coupled N $$ \mathcal{N} $$ = 4 SYM via integrability by Simon Ekhammar, Nikolay Gromov, Paul Ryan

Exact flux vacua, symmetries, and the structure of the landscape by Thomas W. Grimm, Damian van de Heisteeg

Consequences of Gödel theorems on third quantized theories like string field theory and group field theory by Mir Faizal, Arshid Shabir, Aatif Kaisar Khan

“…Such a theory is described on the configuration space of fields rather than spacetime, which is a third quantized theory. So, both string theory and group field theory are third-quantized theories. …”
