A bstract We propose a baryogenenesis mechanism that uses a rotating condensate of a PecceiQuinn (PQ) symmetry breaking field and the dimensionfive operator that gives Majorana neutrino masses. The rotation induces charge asymmetries for the Higgs boson and for lepton chirality through sphaleron processes and Yukawa interactions. The dimensionfive interaction transfers these asymmetries to the lepton asymmetry, which in turn is transferred into the baryon asymmetry through the electroweak sphaleron process. QCD axion dark matter can be simultaneously produced by dynamics of the same PQ field via kinetic misalignment or parametric resonance, favoring an axion decay constant f a ≲ 10 10 GeV, or by conventional misalignment and contributions from strings and domain walls with f a ∼ 10 11 GeV. The size of the baryon asymmetry is tied to the mass of the PQ field. In simple supersymmetric theories, it is independent of UV parameters and predicts the supersymmtry breaking mass scale to be $$ \mathcal{O} $$ O (10 − 10 4 ) TeV, depending on the masses of the neutrinos and whether the condensate is thermalized during a radiation or matter dominated era. The high supersymmetry breaking mass scale may be free from cosmological and flavor/CP problems. Wemore »

The Scale of Supersymmetry Breaking and the Dark Dimension
A bstract We argue for a relation between the supersymmetry breaking scale and the measured value of the dark energy density Λ. We derive it by combining two quantum gravity consistency swampland constraints, which tie the dark energy density Λ and the gravitino mass M 3 / 2 , respectively, to the mass scale of a light KaluzaKlein tower and, therefore, to the UV cutoff of the effective theory. Whereas the constraint on Λ has recently led to the Dark Dimension scenario, with a prediction of a single mesoscopic extra dimension of the micron size, we use the constraint on M 3 / 2 to infer the implications of such a scenario for the scale of supersymmetry breaking. We find that a natural scale for supersymmetry signatures is $$ M=\mathcal{O}\left({\Lambda}^{\frac{1}{8}}\right)=\mathcal{O}\left(\textrm{TeV}\right). $$ M = O Λ 1 8 = O TeV . This mass scale is within reach of LHC and of the next generation of hadron colliders. Finally, we discuss possible string theory and effective supergravity realizations of the Dark Dimension scenario with broken supersymmetry.

A bstract When the SU( N ) $$ \mathcal{N} $$ N = 4 superYangMills (SYM) theory with complexified gauge coupling τ is placed on a round foursphere and deformed by an $$ \mathcal{N} $$ N = 2preserving mass parameter m , its free energy F ( m, τ, $$ \overline{\tau} $$ τ ¯ ) can be computed exactly using supersymmetric localization. In this work, we derive a new exact relation between the fourth derivative $$ {\partial}_m^4F\left(m,\tau, \overline{\tau}\right)\left{{}_m}_{=0}\right. $$ ∂ m 4 F m τ τ ¯ m = 0 of the sphere free energy and the integrated stresstensor multiplet fourpoint function in the $$ \mathcal{N} $$ N = 4 SYM theory.

A bstract We present a search for the dark photon A ′ in the B 0 → A ′ A ′ decays, where A ′ subsequently decays to e + e − , μ + μ − , and π + π − . The search is performed by analyzing 772 × 10 6 $$ B\overline{B} $$ B B ¯ events collected by the Belle detector at the KEKB e + e − energyasymmetric collider at the ϒ(4 S ) resonance. No signal is found in the dark photon mass range 0 . 01 GeV /c 2 ≤ m A ′ ≤ 2 . 62 GeV /c 2 , and we set upper limits of the branching fraction of B 0 → A ′ A ′ at the 90% confidence level.

A bstract The identity of Dark Matter (DM) is one of the most active topics in particle physics today. Supersymmetry (SUSY) is an extension of the standard model (SM) that could describe the particle nature of DM in the form of the lightest neutralino in Rparity conserving models. We focus on SUSY models that solve the hierarchy problem with small fine tuning, and where the lightest SUSY particles $$ \left({\tilde{\upchi}}_1^0,{\tilde{\upchi}}_1^{\pm },{\tilde{\upchi}}_2^0\right) $$ χ ˜ 1 0 χ ˜ 1 ± χ ˜ 2 0 are a triplet of higgsinolike states, such that the mass difference $$ \Delta m\left({\tilde{\upchi}}_2^0,{\tilde{\upchi}}_1^0\right) $$ Δ m χ ˜ 2 0 χ ˜ 1 0 is 0.5–50 GeV. We perform a feasibility study to assess the longterm discovery potential for these compressed SUSY models with higgsinolike states, using vector boson fusion (VBF) processes in the context of protonproton collisions at $$ \sqrt{s} $$ s = 13 TeV, at the CERN Large Hadron Collider. Assuming an integrated luminosity of 3000 fb − 1 , we find that stringent VBF requirements, combined with large missing momentum and one or two low p T leptons, is effective at reducing the major SM backgrounds, leading to a 5 σ (3more »

A bstract We calculate pp → ℓ + ν, ℓ − $$ \overline{\nu} $$ ν ¯ to $$ \mathcal{O} $$ O (1 / Λ 4 ) within the Standard Model Effective Field Theory (SMEFT) framework. In particular, we calculate the fourfermion contribution from dimension six and eight operators, which dominates at large center of mass energy. We explore the relative size of the $$ \mathcal{O} $$ O (1 / Λ 4 ) and $$ \mathcal{O} $$ O (1 / Λ 2 ) results for various kinematic regimes and assumptions about the Wilson coefficients. Results for DrellYan production pp → ℓ + ℓ − at $$ \mathcal{O} $$ O (1 / Λ 4 ) are also provided. Additionally, we develop the form for four fermion contact term contributions to pp → ℓ + ν, ℓ − $$ \overline{\nu} $$ ν ¯ , pp → ℓ + ℓ − of arbitrary mass dimension. This allows us to estimate the effects from even higher dimensional (dimension > 8) terms in the SMEFT framework.
