paper about different robust approach

I can not find any paper about, robust statistics where they are looking to outliers not like a outlierts but like that model miss specification.

i mean that i have sample from N(0,1) ,50 observation and there are value 5 and -4

this 2 are outliers, but TRUE distribution is Caushy and in this case there are not outlieres.

I am looking for paper where autor envisages more possible distribution of errors. And i am looking for some measure of robustness, it is different way like breakdown point.

It is possible to understand me ?

Do you know about something ?
