  The paper con­sid­ers meth­ods of par­ti­cle cool­ing ap­plic­a­ble to beam cool­ing in high en­ergy hadron col­lid­ers at the col­li­sion en­ergy. Presently, there are two major meth­ods of the cool­ing the elec­tron cool­ing and sto­chas­tic cool­ing. The later, in ap­pli­ca­tion to col­lid­ers, re­quires ex­cep­tion­ally large fre­quency band of cool­ing sys­tem. Presently two meth­ods are con­sid­ered. They are the op­ti­cal sto­chas­tic cool­ing (OSC) and the co­her­ent elec­tron cool­ing (CEC). OSC and CEC are es­sen­tially ex­ten­sions of mi­crowave sto­chas­tic cool­ing, op­er­at­ing in 1-10 GHz fre­quency range, to the op­ti­cal fre­quen­cies en­abling bands up to 30-300 THz. The OSC uses un­du­la­tors as a pickup and a kicker, and an op­ti­cal am­pli­fier for sig­nal am­pli­fi­ca­tion, while the CEC uses an elec­tron beam for all these func­tions. We dis­cuss major lim­i­ta­tions, ad­van­tages and dis­ad­van­tages of elec­tron and sto­chas­tic cool­ing sys­tems.
