Loops and trees in generic EFTs

Nathaniel Craig, Minyuan Jiang, Ying-Ying Li +1

We consider aspects of tree and one-loop behavior in a generic 4d EFT of massless scalars, fermions, and vectors, with a particular eye to the high-energy limit of the Standard Mod…

The Four-Loop Cusp Anomalous Dimension from the Sudakov Form Factor

Tobias Huber, Andreas von Manteuffel, Erik Panzer +2

We present an analytic derivation of the full four-loop cusp anomalous dimension of supersymmetric Yang-Mills theory from the Sudakov form factor. To extract the cu…

Effective Field Theory Perspective on Next-to-Minimal Composite Higgs

Yong-Hui Qi, Jiang-Hao Yu, Shou-Hua Zhu

We study both the CP-even and CP-odd effective chiral Lagrangians of next minimal composite Higgs model {with symmetry breaking pattern depicted by the coset } through…

PandaX limits on light dark matter with light mediator in the singlet extension of MSSM

Wenyu Wang, Jia-Jun Wu, Zhao-Hua Xiong +1

Using the latest PandaX limits on light dark matter (DM) with light mediator, we check the implication on the parameter space of the general singlet extension of MSSM (without $Z_3…

A variational approach for many-body systems at finite temperature

Tao Shi, Eugene Demler, J. Ignacio Cirac

We introduce a non-linear differential flow equation for density matrices that provides a monotonic decrease of the free energy and reaches a fixed point at the Gibbs thermal state…

Hidden Analytic Structure of Higgs Amplitudes and Maximal Transcendentality Principle

Qingjun Jin, Gang Yang

We present the computation of two-loop Higgs plus three-parton amplitudes with dimension-seven operators in Higgs effective field theory. The computation is based on the combinatio…
