Probing stops in the coannihilation region at the HL-LHC: a comparative study of different processes
Guang Hua Duan, Xiang Fan, Ken-ichi Hikasa +2
In the minimal supersymmetric model, the coannihilation of the lighter stop and bino-like dark matter provides a feasible way to accommodate the correct dark matt…
Permutation polynomials of degree 8 over finite fields of odd characteristic
Xiang Fan
This paper provides an algorithmic generalization of Dickson's method of classifying permutation polynomials (PPs) of a given degree over finite fields. Dickson's idea is to fo…
Permutation polynomials of degree 8 over finite fields of characteristic 2
Xiang Fan
Up to linear transformations, we obtain a classification of permutation polynomials (PPs) of degree over with . By [J. Number Theory 176 (2017) 466-66],…
The Weil bound and non-exceptional permutation polynomials over finite fields
Xiang Fan
A well-known result of von zur Gathen asserts that a non-exceptional permutation polynomial of degree over exists only if . With the help of the Weil…
A classification of permutation polynomials of degree over finite fields
Xiang Fan
Up to linear transformations, we give a classification of all permutation polynomials of degree over for any odd prime power , with the help of the SageMath…
A minimal extension of MSSM in light of the B decay anomaly
Guang Hua Duan, Xiang Fan, Mariana Frank +2
Motivated by the and anomalies from B decays, we extend the minimal supersymmetric model with a non-universal anomaly-free gauge symmetry, coupling no…
