Modification of the Sommerfeld effect due to coannihilator decays
《Chinese Physics C》2025年第3期1-16,共16页Feng Luo 
Supported by the Sun Yat-sen University Science Foundation。
In dark matter coannihilation scenarios,the Sommerfeld effect of coannihilators is usually important in the calculations of dark matter thermal relic abundance.Due to decays of coannihilators,two annihilating coannihi...

Supersymmetric extension of the minimal dark matter model
《Chinese Physics C》2012年第9期810-817,共8页苌雪 刘纯 马凤才 杨硕 
Supported by National Natural Science Foundation of China (11075193,10821504);National Basic Research Program of China (2010CB833000)
The minimal dark matter model is given a supersymmetric extension. A super SU(2)L quintuplet is introduced with its fermionic neutral component still being the dark matter, and the dark matter mass is about 19.7 TeV...
