Holographic Operator Product Expansion of Loop Operators in Super Yang-Mills Theory
Hong-Zhe Zhang, Wan-Zhe Feng, Jun-Bao Wu
In this paper, we compute the correlation functions of Wilson(-'t~Hooft) loops with chiral primary operators in supersymmetric Yang-Mills theory with gauge…
TF08 Snowmass Report: BSM Model Building
Patrick J. Fox, Graham D. Kribs, Hitoshi Murayama +53
We summarize the state of Beyond the Standard Model (BSM) model building in particle physics for Snowmass 2021, focusing mainly on several whitepaper contributions to BSM model bui…
Explaining the boson mass anomaly and dark matter with a dark sector
Kai-Yu Zhang, Wan-Zhe Feng
The boson mass recently reported by the CDF collaboration shows a deviation from the standard model prediction with an excess at level. We investigate two simple extension…
Hidden sectors and a multi-temperature universe
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath +1
A variety of supergravity and string based models contain hidden sectors which can play a role in particle physics phenomena and in cosmology. In this note we discuss the possibili…
A multi-temperature universe can allow a sub-MeV dark photon dark matter
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath +1
An analysis of sub-MeV dark photon as dark matter is given which is achieved with two hidden sectors, one of which interacts directly with the visible sector while the second has o…
Self-interacting hidden sector dark matter, small scale galaxy structure anomalies, and a dark force
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath +1
The short distance behavior of dark matter (DM) at galaxy scales exhibits several features not explained by the typical cold dark matter (CDM) with velocity-independent cross-secti…
Twin Cogenesis
Wan-Zhe Feng, Jiang-Hao Yu
We investigate a cogenesis mechanism within the twin Higgs setup which can naturally explain the nature of dark matter, the cosmic coincidence puzzle, little hierarchy problem, lep…
Expanding the parameter space of natural supersymmetry
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath
SUSY/SUGRA models with naturalness defined via small are constrained due to experiment on the relic density and the experimental limits on the WIMP-proton cross-section and WIM…
A long-lived stop with freeze-in and freeze-out dark matter in the hidden sector
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath
In extended supersymmetric models with a hidden sector the lightest -parity odd particle can reside in the hidden sector and act as dark matter. We consider the case when the hi…
Baryogenesis and Dark Matter in Extensions
Wan-Zhe Feng, Pran Nath
A brief review is given of some recent works where baryogenesis and dark matter have a common origin within the extensions of the standard model and of the minimal supersymm…
Dirac dark matter and with gauge symmetry
Alejandro Celis, Wan-Zhe Feng, Martin Vollmann
We revisit the possibility of a Dirac fermion dark matter candidate in the light of current anomalies by investigating a minimal extension of the Standard M…
Stringy explanation of anomalies
Alejandro Celis, Wan-Zhe Feng, Dieter Lust
We show that the recent anomalies in transitions observed by the LHCb collaboration can be accommodated within string motivated models with a low mass $Z^{\…
ATLAS Diboson Excess from Stueckelberg Mechanism
Wan-Zhe Feng, Zuowei Liu, Pran Nath
We discuss the diboson excess seen by the ATLAS detector around 2 TeV in the LHC run I at TeV. We explore the possibility that such an excess can arise from a bos…
String Resonances at Hadron Colliders
Luis A. Anchordoqui, Ignatios Antoniadis, De-Chang Dai +6
[Abridged] We consider extensions of the standard model based on open strings ending on D-branes. Assuming that the fundamental string mass scale M_s is in the TeV range and that t…
Building a Stückelberg Portal
Wan-Zhe Feng, Gary Shiu, Pablo Soler +1
We construct explicit string theory models realizing the recently proposed "Stückelberg Portal" scenario, a framework for building Z' mediation models without the need to introduce…
Probing Hidden Sectors with Stückelberg U(1) Gauge Fields
Wan-Zhe Feng, Gary Shiu, Pablo Soler +1
We propose a framework in which visible matter interacts with matter from a hidden sector through mass mixings of Stückelberg U(1) gauge fields. In contrast to other Z' mediation s…
Cogenesis in a universe with vanishing within a gauged extension
Wan-Zhe Feng, Pran Nath
We consider a gauged extension of the standard model and of the minimal supersymmetric standard model where the dark matter fields are charged under and carry lep…
Higgs diphoton rate and mass enhancement with vector-like leptons and the scale of supersymmetry
Wan-Zhe Feng, Pran Nath
Analysis of contributions from vector-like leptonic supermultiplets to the Higgs diphoton decay rate and to the Higgs boson mass is given. Corrections arising from the exchange of…
Baryogenesis from dark matter
Wan-Zhe Feng, Anupam Mazumdar, Pran Nath
We consider the possibility that some primordial fields decay purely into the dark sector creating asymmetric dark matter. This asymmetry is subsequently transmuted into leptons an…
Cosmic Coincidence and Asymmetric Dark Matter in a Stueckelberg Extension
Wan-Zhe Feng, Pran Nath, Gregory Peim
We discuss the possibility of cogenesis generating the ratio of baryon asymmetry to dark matter in a Stueckelberg U(1) extension of the standard model and of the minimal supersymme…
Massive Supermultiplets in Four-Dimensional Superstring Theory
Wan-Zhe Feng, Dieter Lust, Oliver Schlotterer
We extend the discussion of arXiv:1007.5254 on massive Regge excitations on the first mass level of four-dimensional superstring theory. For the lightest massive modes of the open…

Wan-Zhe Feng, Tomasz R. Taylor
We study higher level Regge resonances of open superstrings, focusing on the universal part of the Neveu-Schwarz sector common to all D-brane realizations of the standard model. Fo…
Searching for string resonances in e^+e^- and γγcollisions
Luis A. Anchordoqui, Wan-Zhe Feng, Haim Goldberg +2
