    On the two-loop BSM corrections to $$h\longrightarrow \gamma \gamma $$ h ⟶ γ γ in a triplet extension of the SM by Giuseppe Degrassi, Pietro Slavich

    Published 2025-01-01
    “…We focus on the two-loop corrections controlled by the quartic scalar couplings, and obtain explicit and compact formulas for the $$h \gamma \gamma $$ h γ γ amplitude by means of a low-energy theorem that connects it to the derivative of the photon self-energy w.r.t. the Higgs field. We briefly discuss the numerical impact of the newly-computed contributions, showing that they may be required for a precise determination of $$\Gamma [h\rightarrow \gamma \gamma ]$$ Γ [ h → γ γ ] in scenarios where the quartic scalar couplings are large.…”

    Quantum secure communication algorithm based on cyclic code and information compression by Hongyang MA, Xin ZHANG, Peng’ao XU, Fen LIU, Xingkui FAN

    Published 2020-03-01
    “…For the problem that the classical secure communication was challenging to transmit information,a quantum secure communication algorithm based on cyclic code and information compression was proposed.First,the data was encoded into two sets of data with different lengths by the sender,one set of data was used for cycling coding and the other one was used to compress coding.Second,single-photon sequence was transmitted to the receiver on the quantum channel by the sender.The error number was used as the basis of channel security detection.If the channel was secure,quantum states were encoded for the data,and segment transmitted by quantum stabilizer codes.The error caused by the environment can be overcome according to characteristic of the stable code.Finally,the information was decoded after receiving the quantum information,then recirculated and decompressed to obtain data.The security analysis shows that the quantum secure communication algorithm can resist the attack of jamming and spoofing attacked.The simulation results show that good results can be obtained to 5 segments for data compression.…”
